suppletion

An irregular paradigm is one in which the derived forms of a word cannot be deduced by simple rules from the base form. For example, someone who knows only a little English can deduce that the plural of girl is girls but cannot deduce that the plural of man is men. Language learners are often most aware of irregular verbs, but any part of speech with inflections can be irregular.

For most synchronic purposes—first-language acquisition studies, psycholinguistics, language-teaching theory—it suffices to note that these forms are irregular. However, historical linguistics seeks to explain how they came to be so and distinguishes different kinds of irregularity according to their origins.

Most irregular paradigms (like man:men) can be explained by phonological developments that affected one form of a word but not another (in this case, Germanic umlaut). In such cases, the historical antecedents of the current forms once constituted a regular paradigm.

Historical linguistics uses the term "suppletion"

{{OED | suppletion}}

to distinguish irregularities like person:people or cow:cattle that cannot be so explained because the parts of the paradigm have not evolved out of a single form.

Hermann Osthoff coined the term "suppletion" in German in an 1899 study of the phenomenon in Indo-European languages.{{cite book|last=Osthoff |first=Hermann|title=Vom Suppletivwesen der indogermanischen Sprachen : erweiterte akademische Rede ; akademische Rede zur Feier des Geburtsfestes des höchstseligen Grossherzogs Karl Friedrich am 22.

Suppletion exists in many languages around the world.{{Cite book|title=Suppletion: Typology, markedness, complexity|last=Greville G|first=Corbett|publisher=On Inflection. Trends in Linguistics: Studies and Monographs, Berlin, Mouton de Gruyter|year=2009|location=Berlin|pages=25–40}} These languages are from various language families: Indo-Aryan, Dravidian, Semitic, Romance, etc.

For example, in Georgian, the paradigm for the verb "to come" is composed of four different roots ({{Lang|ka-Latn|mi-}}, {{Lang|ka-Latn|-val-}}, {{Lang|ka-Latn|-vid-}}, and {{Lang|ka-Latn|-sul-}}; {{lang|ka|მი-}}, {{lang|ka|-ვალ-}}, {{lang|ka|-ვიდ-}}, {{lang|ka|-სულ-}}).Andrew Hippisley, Marina Chumakina, Greville G. Corbett and Dunstan Brown. Suppletion: Frequency, Categories and Distribution of Stems. University of Surrey.[http://epubs.surrey.ac.uk/2229/]

Similarly, in Modern Standard Arabic, the verb {{Transliteration|ar|jāʾ}} ('come') usually uses the form {{Transliteration|ar|taʿāl}} for its imperative, and the plural of {{Transliteration|ar|marʾah}} ('woman') is {{Transliteration|ar|nisāʾ}}.

Some of the more archaic Indo-European languages are particularly known for suppletion. Ancient Greek, for example, has some twenty verbs with suppletive paradigms, many with three separate roots.

In English, the past tense of the verb go is went, which comes from the past tense of the verb wend, archaic in this sense. (The modern past tense of wend is wended.) See Go (verb).

The Romance languages have a variety of suppletive forms in conjugating the verb "to go", as these first-person singular forms illustrate (second-person singular forms in imperative):However, some unstandardized languages are chosen in non-standard dialects instead based on their uniqueness. This table below excludes periphrastic tenses.

The sources of these forms, numbered in the table, are six different Latin verbs:

1. {{lang|la|vādere}} ‘to go, proceed’,Vadere is cognate with English wade (PIE root *weh₂dʰ-).
2. {{lang|la|īre}} ‘to go’
3. {{lang|la|ambitāre}} ‘to go around’,Late Lat. *ambitāre is a frequentative form of classical ambio ‘to go around’. also the source for Spanish and Portuguese {{lang|es|andar}} ‘to walk’
4. {{lang|la|ambulāre}} ‘to walk’, or perhaps another Latin root, a Celtic root, or a Germanic root {{lang|frk|halon}} or {{lang|non|hala}}{{Cite journal |title=A New Hypothesis on the Origin of French Aller |author= H. Diamant |year=1968 |journal=Word |volume=24 |number=1–3 |pages=73–80 |publisher=Routledge |doi=10.1080/00437956.1968.11435516 |doi-access=free }}
5. {{lang|la|fuī}} suppletive perfective of {{lang|la|esse}} ‘to be’.The preterites of "to be" and "to go" are identical in Spanish and Portuguese. Compare the English construction "Have you been to France?" which has no simple present form.
6. {{lang|la|meāre}} ‘to go along’.

Many of the Romance languages use forms from different verbs in the present tense; for example, French has {{lang|fr|je vais}} ‘I go’ from {{lang|la|vadere}}, but {{lang|fr|nous allons}} ‘we go’ from {{lang|la|ambulare}}. Galician-Portuguese has a similar example: {{lang|gl|imos}} from {{lang|la|ire}} ‘to go’ and {{lang|gl|vamos}} from {{lang|la|vadere}} ‘we go’; the former is somewhat disused in modern Portuguese but very alive in modern Galician. Even {{lang|gl|ides}}, from {{lang|la|itis}} second-person plural of {{lang|la|ire}}, is the only form for ‘you (plural) go’ both in Galician and Portuguese (Spanish {{lang|es|vais}}, from {{lang|la|vadere}}).

Sometimes, the conjugations differ between dialects. For instance, the Limba Sarda Comuna standard of Sardinian supported a fully regular conjugation of {{lang|sc|andare}}, but other dialects like Logudorese do not (see also Sardinian conjugation). In Romansh, Rumantsch Grischun substitutes present and subjunctive forms of ir with vom and giaja (both are from Latin vādere and īre, respectively) in the place of mon and mondi in Sursilvan.

Similarly, the Welsh verb {{lang|cy|mynd}} ‘to go’ has a variety of suppletive forms such as {{lang|cy|af}} ‘I shall go’ and {{lang|cy|euthum}} ‘we went’. Irish {{lang|cy|téigh}} ‘to go’ also has suppletive forms: {{lang|cy|dul}} ‘going’ and {{lang|cy|rachaidh}} ‘will go’.

In Estonian, the inflected forms of the verb {{lang|et|minema}} ‘to go’ were originally those of a verb cognate with the Finnish {{lang|fi|lähteä}} ‘to leave’, except for the passive and infinitive.

In Germanic, Romance (except Romanian), Celtic, Slavic (except Bulgarian and Macedonian), and Indo-Iranian languages, the comparative and superlative of the adjective "good" is suppletive; in many of these languages the adjective "bad" is also suppletive.

{{notelist}}

The comparison of "good" is also suppletive in {{langx|et|hea}} → {{lang|et|parem}} → {{lang|et|parim}} and {{langx|fi|hyvä}} → {{lang|fi|parempi}} → {{lang|fi|paras}}.

{{notelist}}

Similarly to the Italian noted above, the English adverb form of "good" is the unrelated word "well", from Old English {{lang|ang|wel}}, cognate to {{lang|ang|wyllan}} "to wish".

{{Main|Ancient Greek verbs#Verbs using more than one stem}}

Ancient Greek had a large number of suppletive verbs. A few examples, listed by principal parts:

:*erkhomai, eîmi/eleusomai, ēlthon, elēlutha, —, — "go, come".

:*legō, eraō (erô) / leksō, eipon / eleksa, eirēka, eirēmai / lelegmai, elekhthēn / errhēthēn "say, speak".

:*horaō, opsomai, eidon, heorāka / heōrāka, heōrāmai / ōmmai, ōphthēn "see".

:*pherō, oisō, ēnegka / ēnegkon, enēnokha, enēnegmai, ēnekhthēn "carry".

:*pōleō, apodōsomai, apedomēn, peprāka, peprāmai, eprāthēn "sell".

In Bulgarian, the word {{langx|bg|човек|chovek|label=none}} ("man", "human being") is suppletive. The strict plural form, {{langx|bg|човеци|chovetsi|label=none}}, is used only in Biblical context (like "brethren" as the archaic or symbolic plural of "brother" in English). In modern usage it has been replaced by the Greek loan {{langx|el|хора|khora|label=none}}. The counter form (the special form for masculine nouns, used after numerals) is suppletive as well: {{langx|bg|души|dushi|label=none}} (with the accent on the first syllable). For example, {{langx|bg|двама, трима души|dvama, trima dushi|label=none}} ("two, three people"); this form has no singular either. (A related but different noun is the plural {{langx|bg|души|dushi|label=none}}, singular {{langx|bg|душа|dusha|label=none}} ("soul"), both with accent on the last syllable.)

In English, the complicated irregular verb to be has forms from several different roots:

• be, been, being—from Old English bēon ("to be, become"), from Proto-Germanic *beuną ("to be, exist, come to be, become"), from Proto-Indo-European *bʰúHt (“to grow, become, come into being, appear”), from the root *bʰuH- ("to become, grow, appear").
• am, is, are—from Middle English am, em, is, aren, from Old English eam, eom, is, earun, earon, from Proto-Germanic *immi, *izmi, *isti, *arun, all forms of the verb *wesaną ("to be; dwell"), from Proto-Indo-European *h₁ésmi ("I am, I exist"), from the root *h₁es- ("to be").
• was, were—from Old English wæs, wǣre, from Proto-Germanic *was, *wēz, from the Proto-Indo-European root *h₂wes- ("to dwell, reside")

This verb is suppletive in most Indo-European languages, as well as in some non-Indo-European languages such as Finnish.

An incomplete suppletion exists in English with the plural of person (from the Latin {{lang|la|persona}}). The regular plural persons occurs mainly in legalistic use. More commonly, the singular of the unrelated noun people (from Latin {{lang|la|populus}}) is used as the plural; for example, "two people were living on a one-person salary" (note the plural verb). In its original sense of "populace, ethnic group", people is itself a singular noun with regular plural peoples.

• The verb "to be": {{lang|hu|van}} ("there is"), {{lang|hu|vagyok}}, {{lang|hu|vagy}} ("I am", "you are"), {{lang|hu|lenni}} ("to be"), {{lang|hu|lesz}} ("will be"), {{lang|hu|nincs}}, {{lang|hu|sincs}} ("there is not", "there is neither", replacing {{lang|hu|nem}} + {{lang|hu|van}} and {{lang|hu|sem}} + {{lang|hu|van}} respectively).
• The verb {{lang|hu|jön}} ("come") has the imperative {{lang|hu|gyere}} (the regular {{lang|hu|jöjj}} is dated).
• The numeral {{lang|hu|sok}} ("many/a lot") has the comparative {{lang|hu|több}} and the superlative {{lang|hu|legtöbb}}.
• The adverb {{lang|hu|kicsit}} ("a little") has the comparative {{lang|hu|kevésbé}} and the superlative {{lang|hu|legkevésbé}}.
• Many inflected forms of personal pronouns are formed by using the suffix as the base: {{lang|hu|nekem}} ("to me") from {{lang|hu|-nak/-nek}} (dative suffix) and {{lang|hu|-em}} (first person singular possessive suffix). Even among these, the superessive form ("on") uses the root {{lang|hu|rajta}} instead of the suffix {{lang|hu|-on/-en/-ön}}.
• The numerals {{lang|hu|egy}}, {{lang|hu|kettő}} ("one", "two") have the ordinal forms {{lang|hu|első}}, {{lang|hu|második}} ("first", "second"). However they are regular in compounds: {{lang|hu|tizenegyedik}}, {{lang|hu|tizenkettedik}} ("eleventh", "twelfth").

Several irregular Irish verbs are suppletive:

• abair (to say): derived from Old Irish as·beir, from Proto-Indo-European roots *h₁eǵʰs- ("out") and *bʰer- ("bear, carry"). However, the verbal noun rá is derived from Old Irish rád, ultimately from Proto-Indo-European *reh₂dʰ- ("perform successfully").
• bí (to be): derived from Proto-Indo-European *bʰuH- ("grow, become, come into being, appear"). However, the present tense form tá is derived from Old Irish at·tá, from Proto-Celtic *ad-tāyeti, ultimately from Proto-Indo-European *steh₂- ("stand").
• beir (to catch): derived from Proto-Indo-European *bʰer- ("bear, carry"). However, the past tense form rug is derived from Old Irish rouic, which is from Proto-Celtic *ɸro-ōnkeyo-, ultimately from Proto-Indo-European roots *pro- ("forth, forward") and *h₂neḱ- ("reach").
• feic (to see): derived from Old Irish aicci, from Proto-Indo-European *kʷey- ("observe"). However, the past tense form chonaic is derived from Old Irish ad·condairc, ultimately from Proto-Indo-European *derḱ₂- ("see").
• téigh (to go): derived from Old Irish téit, from Proto-Indo-European *stéygʰeti- ("to be walking, to be climbing"). However, the future form rachaidh is derived from Old Irish regae, ultimately from Proto-Indo-European *h₁r̥gʰ- ("go, move"), while the verbal noun dul is from *h₁ludʰét ("arrive").

There are several suppletive comparative and superlative forms in Irish; in addition to the ones listed above, there is:

• fada, "long"; comparative níos faide or níos sia — fada is from Old Irish fota, from Proto-Indo-European *wasdʰos (“long, wide”); compare Latin vāstus (“wide”), while sia is from Old Irish sír ("long, long-lasting"), from Proto-Celtic *sīros (“long”); compare Welsh/Breton hir.{{Cite web|url=http://www.dil.ie/37651|title=eDIL - Irish Language Dictionary|website=www.dil.ie}}{{Cite web|url=http://nualeargais.ie/gnag/adjekt2.htm|title=Comparative forms|website=nualeargais.ie}}{{Cite web|url=http://www.potafocal.com/beo/?s=sia|title=Pota Focal | sia|website=Pota Focal}}{{Cite book|url=https://books.google.com/books?id=zxfNCQAAQBAJ&q=%22n%C3%ADos+sia%22&pg=PT648|title=Impreasin na Gaeilge I – Z: (Fuaim na Gaeilge)|first=Seosamh Mac|last=Ionnrachtaigh|date=June 2, 2015|publisher=AuthorHouse|isbn=9781496984203|via=Google Books}}

In modern Japanese, the copulae だ, である and です take な to create "attributive forms" of adjectival nouns{{cite web|url=https://kotobank.jp/word/%E5%BD%A2%E5%AE%B9%E5%8B%95%E8%A9%9E-59186#w-59186|website=Kotobank|title=形容動詞}} (hence the English moniker, "na-adjectives"):

The "conclusive" and "attributive" forms, だ and な, were constructed similarly, from a combination of a particle and an inflection form of the old verb あり (ari, "to exist").

• で + あり ("conclusive") → であり → であ → だ{{cite web|url=https://kotobank.jp/word/%E3%81%A0-556047#w-556054|website=Kotobank|title=だ}}
• に + ある ("attributive") → なる → なん → な{{cite web|url=https://kotobank.jp/word/%E3%81%AA-586863#w-2069724|website=Kotobank|title=な}}

(Note: で itself was also a contraction of earlier にて.{{cite web|url=https://kotobank.jp/word/%E3%81%A7-573220#w-2054769|website=Kotobank|title=で}})

In modern Japanese, である ("conclusive") simply retains the older appearance of だ, while です is a different verb that can be used as a suppleted form of だ. Multiple hypotheses have been proposed for the etymology of です, one of which is a contraction of であります:{{cite web|url=https://kotobank.jp/word/%E3%81%A7%E3%81%99-575878|website=Kotobank|title=です}}

• で + あり ("adverbial") + ます → であります → です

The basic construction of the negative form of a Japanese verb is the "irrealis" form followed by ない, which would result in such hypothetical constructions as *だらない and *であらない. However, these constructions are not used in modern Japanese, and the construction ではない is used instead.{{cite book|page=15|chapter=Verbs|title=Handbook of Modern Japanese Grammar|last=Matsuoka McClain|first=Yoko|publisher=The Hokuseido Press|location=Tokyo|year=1983|edition=6th}} This is because *あらない, the hypothetically regular negative form of ある, is not used either, and is simply replaced with ない.

• あら ("irrealis") + ない → ない
• であら ("irrealis") + ない → ではない
• だら ("irrealis") + ない → ではない → じゃない

While the auxiliary ない causes suppletion, other auxiliaries such as ん and ありません do not necessarily.

• あら ("irrealis") + ん → あらん
• あり ("adverbial") + ませ + ん → ありません
• であり ("adverbial") + ませ + ん → でありません

For です, its historical "irrealis" form, でせ has not been attested to create a negative form (only でせう → でしょう has been attested, and there were and are no *でせん and *でせない).{{cite book|page=508|title=日本語文法大辞典|last=Yamaguchi|first=Akiho|last2=秋山|first2=守英|publisher=Meiji Shoin|date=1 March 2001}} Thus, it has to borrow でありません as its negative form instead.

To express a potential meaning, as in "can do", most verbs use the "irrealis" form followed by れる or られる. する, notably has no such construction, and has to use a different verb for this meaning, できる.

{{Main|Latin conjugation}}Latin has several suppletive verbs. A few examples, listed by principal parts:

:*sum, esse, fuī, futūrus - "be".

:*ferō, ferre, tulī or tetulī, lātus - "carry, bear".

:*fīō, fierī, factus sum (suppletive and semi-deponent) - "become, be made, happen"

In some Slavic languages, a few verbs have imperfective and perfective forms arising from different roots. For example, in Polish:

Note that {{lang|pl|z—}}, {{lang|pl|przy—}}, {{lang|pl|w—}}, and {{lang|pl|wy—}} are prefixes and are not part of the root

In Polish, the plural form of {{lang|pl|rok}} ("year") is {{lang|pl|lata}} which comes from the plural of {{lang|pl|lato}} ("summer"). A similar suppletion occurs in {{langx|ru|год|god}} ("year") > {{langx|ru|лет|let|label=none}} (genitive of "years").

The Romanian verb {{lang|ro|a fi}} ("to be") is suppletive and irregular, with the infinitive coming from Latin fieri, but conjugated forms from forms of already suppletive Latin sum. For example, {{lang|ro|eu sunt}} ("I am"), {{lang|ro|tu ești}} ("you are"), {{lang|ro|eu am fost}} ("I have been"), {{lang|ro|eu eram}} ("I used to be"), {{lang|ro|eu fusei/fui}} ("I was"); while the subjunctive, also used to form the future in {{lang|ro|o să fiu}} ("I will be/am going to be"), is linked to the infinitive.

In Russian, the word {{langx|ru|человек|chelovek|label=none}} ("man, human being") is suppletive. The strict plural form, {{langx|ru|человеки|cheloveki|label=none}}, is used only in Orthodox Church contexts, with numerals (e. g. {{langx|ru|пять человек|pyat chelovek|label=none}} "five people") and in humorous context. It may have originally been the unattested {{langx|ru|*человекы|*cheloveky|label=none}}. In any case, in modern usage, it has been replaced by {{langx|ru|люди|lyudi|label=none}}, the singular form of which is known in Russian only as a component of compound words (such as {{langx|ru|простолюдин|prostolyudin|label=none}}). This suppletion also exists in Polish ({{lang|pl|człowiek}} > {{lang|pl|ludzie}}), Czech ({{lang|cs|člověk}} > {{lang|cs|lidé}}), Serbo-Croatian ({{lang|sr|čovjek}} > {{lang|sr|ljudi}}),{{cite book |last=Kordić |first=Snježana |author-link=Snježana Kordić |editor1-last=Tatarin |editor1-first=Milovan |title=Zavičajnik: zbornik Stanislava Marijanovića: povodom sedamdesetogodišnjice života i četrdesetpetogodišnjice znanstvenoga rada |publisher=Sveučilište Josipa Jurja Strossmayera, Filozofski fakultet |page=191 |language=sh |chapter=Gramatička kategorija broja |trans-chapter=Grammatical category of number |chapter-url=http://bib.irb.hr/datoteka/426600.GRAMATICKA_KATEGORIJA_BR.PDF |archive-url=https://ghostarchive.org/archive/20221009/http://bib.irb.hr/datoteka/426600.GRAMATICKA_KATEGORIJA_BR.PDF |archive-date=2022-10-09 |url-status=live |location=Osijek |year=2005 |isbn=953-6456-54-0 |oclc=68777865 |s2cid=224274961 |ssrn=3438755 |id={{CROSBI|426600}} |access-date=22 September 2021}} Slovene ({{lang|sl|človek}} > {{lang|sl|ljudje}}), and Macedonian ({{lang|mk|човек}} ({{transliteration|mk|čovek}}) > {{lang|mk|луѓе}} ({{transliteration|mk|lugje}})).

Strictly speaking, suppletion occurs when different inflections of a lexeme (i.e., with the same lexical category) have etymologically unrelated stems. The term is also used in looser senses, albeit less formally.

The term "suppletion" is also used in the looser sense when there is a semantic link between words but not an etymological one; unlike the strict inflectional sense, these may be in different lexical categories, such as noun/verb.Paul Georg Meyer (1997) Coming to know: studies in the lexical semantics and pragmatics of academic English, p. 130: "Although many linguists have referred to [collateral adjectives] (paternal, vernal) as 'suppletive' adjectives with respect to their base nouns (father, spring), the nature of ..."Aspects of the theory of morphology, by Igor Mel’čuk, [https://books.google.com/books?id=k_GtOxicc0QC&dq=%22suppletive+adjectives%22&pg=PA461 p. 461]

English noun/adjective pairs such as father/paternal or cow/bovine are also referred to as collateral adjectives. In this sense of the term, father/fatherly is non-suppletive. Fatherly is derived from father, while father/paternal is suppletive. Likewise cow/cowish is non-suppletive, while cow/bovine is suppletive.

In these cases, father/pater- and cow/bov- are cognate via Proto-Indo-European, but 'paternal' and 'bovine' are borrowings into English (via Old French and Latin). The pairs are distantly etymologically related, but the words are not from a single Modern English stem.

The term "weak suppletion" is sometimes used in contemporary synchronic morphology in reference to sets of stems whose alternations cannot be accounted for by synchronically productive phonological rules. For example, the two forms child/children are etymologically from the same source, but the alternation does not reflect any regular morphological process in modern English: this makes the pair appear to be suppletive, even though the forms go back to the same root.

In that understanding, English has abundant examples of weak suppletion in its verbal inflection: e.g. bring/brought, take/took, see/saw, etc. Even though the forms are etymologically related in each pair, no productive morphological rule can derive one form from the other in synchrony. Alternations just have to be learned by speakers — in much the same way as truly suppletive pairs such as go/went.

Such cases, which were traditionally simply labelled "irregular", are sometimes described with the term "weak suppletion", so as to restrict the term "suppletion" to etymologically unrelated stems.

• Collateral adjective—denominal adjectives based on a suppletive root, such as arm ~ brachial
• Irregular verb
