infix

English has almost no true infixes and those it does have are marginal. Most are heard in colloquial speech;{{Cite web |last=Luu |first=Chi |date=2015-04-28 |title=Fanf-kingtastic and Edumacational: The Case of English Infixation |url=https://daily.jstor.org/fanfuckingtastic-and-edumacational-the-case-of-english-infixation/ |access-date=2023-02-17 |website=JSTOR Daily |language=en-US}} although there are other examples, such as in technical terminology, these examples are often more accurately described as tmesis.{{Cite journal |last=McMillan |first=James B. |date=1980 |title=Infixing and Interposing in English |url=https://www.jstor.org/stable/455082 |journal=American Speech |volume=55 |issue=3 |pages=163–183 |doi=10.2307/455082 |jstor=455082 |issn=0003-1283|url-access=subscription }}

None of the following are recognized in standard English.

• The infix {{infix|-iz-}} or {{infix|-izn-}} is characteristic of hip-hop slang, for example h-iz-ouse for house and sh-izn-it for shit.
• The {{infix|-ma-}} infix (or "Homeric infix," after Homer Simpson),{{Harvnb|Yu|2004}} gives a word an ironic pseudo-sophistication, as in sophisti-ma-cated (sophisticated), saxo-ma-phone, (saxophone) and edu-ma-cation. (education) This exists as a slang phenomenon.
• Infixes also occur in some language games.
• The use of 'expletive infixes' such as -fucking- and -bloody-, which are words rather than affixes, is known as tmesis.

{{main|Nasal infix}}

The present tense of some Proto-Indo-European verbs, in the case of a certain number of roots, adds a nasal infix (m, n) to the basic root. The stems of the other tenses have the root without the infix, and thus these verbs are called nasal-presents. This phenomenon is inherited, and preserved to varying degrees, by some early daughter languages such as Sanskrit, Ancient Greek, Latin language, etc.{{Harvnb|Fortson|2010|loc=§5.25}}

• Sanskrit exhibits the greatest transparency of this feature amongst the Indo-European languages, with the phenomenon manifesting in three of the ten traditional verb classes, where the infix is higher-grade and accent-bearing in the strong forms, and reduced-grade in the weak forms.{{Harvnb|Szemerényi|1996|loc=§9.4.1.3}}{{Harvnb|Burrow|2001|p=289}} For example, {{lang|sa|√yuj-}}, 'join' has {{lang|sa|yu·ná·k·ti}} 's/he joins' ↔ {{lang|sa|yu·ñj·ánti}}, 'they join'.{{Harvnb|Burrow|2001|loc=§7.8}}

• Latin present {{lang|la|vincō}} "I win" (cf. perfect passive participle {{lang|la|victus}} "conquered"){{L&S|vinco|ref}}
• Ancient Greek {{lang|grc|lambánō}} (also with {{lang|grc|-an-}} suffix) "I take" (cf. aorist {{lang|grc|élǎbon}} "I took"){{LSJ|lamba/nw|λαμβάνω|ref}}

In Nicaraguan, Costa Rican, and Honduran Spanish, the Spanish diminutive affix becomes an infix {{infix|it}} in names: {{lang|es|Óscar}} {{IPA|[ˈoskar]}} → {{lang|es|Osquítar}} {{IPA|[osˈkitar]}} (cf. standard {{lang|es|Oscarito}}); {{lang|es|Edgar}} → {{lang|es|Edguítar}}; {{lang|es|Victor}} → {{lang|es|Victítor}}. This diminutive infix can also be found for the word {{lang|es|azúcar}}, due to its unusual form as a paroxytone word with a final /r/, giving {{lang|es|azuquítar}}.{{cite book

Arabic uses a common infix, {{infix|t}} {{lang|ar|ت}} for Form VIII verbs, usually a reflexive of Form I. It is placed after the first consonant of the root; an epenthetic i- prefix is also added, since words cannot begin with a consonant cluster. An example is {{lang|ar|اجتهد}} {{lang|ar|ijtahada}} "he worked hard", from {{lang|ar|جهد}} {{lang|ar|jahada}} "he strove". (The words {{lang|ar|ijtihad}} and {{lang|ar|jihad}} are nouns derived from these two verbs.)

Infixes are common in some Austronesian and Austroasiatic languages, but not in others. For example, in Tagalog, a grammatical form similar to the active voice is formed by adding the infix {{infix|um}} near the beginning of a verb. The most common infix is {{infix|in}} which marks the perfect aspect, as in '{{lang|tl|giniba|italic=no}}', meaning 'ruined' (from '{{lang|tl|giba}}', an adjective meaning 'worn-out'); '{{lang|tl|binato}}', meaning 'stoned' (from '{{lang|tl|bato}}', 'stone'); and '{{lang|tl|ginamit}}', meaning 'used'{{vague|say from what word.|date=February 2025}}. Tagalog has borrowed the English word graduate as a verb; to say "I graduated" a speaker uses the derived form {{lang|tl|grumaduate}}.

Khmer, an Austroasiatic language, has seven different infixes. They include the nominalizing infix {{infix|b}}, which derives {{lang|km|lbɨən}} 'speed' from {{lang|km|lɨən}} 'fast' and {{lang|km|lbɑɑng}} ' trial' from {{lang|km|lɔɔng}} 'to test, to haunt', or the agentive {{infix|m}} deriving {{lang|km|cmam}} 'watchman' from {{lang|km|cam}} 'to watch'. These elements are no longer productive, and occur crystallized in words inherited from Old Khmer.

In Malay and Indonesian, there are three infixes (sisipan), {{infix|el}}, {{infix|em}}, and {{infix|er}}. All infixes are no longer productive and cannot be used to derive new words.

Examples include:

• The word 'gembung' (variant of 'kembung') means "bloated", while 'gelembung' means "bubble"'.
• The word 'cerlang' means "luminous", while 'cemerlang' means "brilliant"'.
• The word 'gigi' means "tooth", while 'gerigi' means "serration"'.

In Seri, some verbs form the plural stem with infixation of {{infix|tóo}} after the first vowel of the root; compare the singular stem ic 'plant (verb)' with the plural stem itóoc. Examples: itíc 'did s/he plant it?' and ititóoc 'did they sow it?'.

Tmesis, the use of a lexical word rather than an affix, is sometimes considered a type of infixation. These are the so-called "expletive infixes", as in abso-bloody-lutely. Since these are not affixes{{Citation needed|date=May 2022}}, they are commonly disqualified from being considered infixes.

Sequences of adfixes (prefixes or suffixes) do not result in infixes: an infix must be internal to a word stem. Thus, the word originally, formed by adding the suffix -ly to original, does not turn the suffix -al into an infix. There is simply a sequence of two suffixes, origin-al-ly. In order for -al- to be considered an infix, it would have to have been inserted in the non-existent word *originly. The "infixes" in the tradition of Bantu linguistics are often sequences of prefixes of this type, though there may be debate over specific cases.

The Semitic languages have a form of ablaut (changing the vowels within words, as in English sing, sang, sung, song) that is sometimes called infixation, as the vowels are placed between the consonants of the root. However, this interdigitation of a discontinuous root with a discontinuous affix is more often called transfixation.

An interfix joins a compound word, as in speed-o-meter.

When glossing, it is conventional to set off infixes with {{angle bracket|angle brackets}}, rather than the hyphens used to set off prefixes and suffixes:

:sh{{infix|izn}}it, saxo{{infix|ma}}phone, pi{{infix|pe}}coline

Compare:

:origin-al-ly

which contains the suffix -ly added to the word original, which is itself formed by adding the suffix -al to the root origin.
