mutual intelligibility

In linguistics, mutual intelligibility is a relationship between different but related language varieties in which speakers of the different varieties can readily understand each other without prior familiarity or special effort. Mutual intelligibility is sometimes used to distinguish languages from dialects, although sociolinguistic factors are often also used.

Intelligibility between varieties can be asymmetric; that is, speakers of one variety may be able to better understand another than vice versa. An example of this is the case between Afrikaans and Dutch. It is generally easier for Dutch speakers to understand Afrikaans than for Afrikaans speakers to understand Dutch. (See {{section link|Afrikaans#Mutual intelligibility with Dutch}}).

In a dialect continuum, neighbouring varieties are mutually intelligible, but differences mount with distance, so that more widely separated varieties may not be mutually intelligible. Intelligibility can be partial, as is the case with Azerbaijani and Turkish, or significant, as is the case with Bulgarian and Macedonian. However, sign languages, such as American and British Sign Language, usually do not exhibit mutual intelligibility with each other.

Types

=Asymmetric intelligibility=

Asymmetric intelligibility refers to two languages that are considered partially mutually intelligible, but for various reasons, one group of speakers has more difficulty understanding the other language than the other way around. For example, if one language is related to another but has simplified its grammar, the speakers of the original language may understand the simplified language, but not vice versa. To illustrate, Dutch speakers tend to find it easier to understand Afrikaans as a result of Afrikaans's simplified grammar.

=Among sign languages=

Sign languages are not universal and usually not mutually intelligible,{{cite web | publisher = Linguistic society |title= What is Sign Language?|url= https://www.linguisticsociety.org/content/what-sign-language|access-date=10 March 2018|url-status=live |archive-url=https://web.archive.org/web/20180213195125/https://www.linguisticsociety.org/content/what-sign-language|archive-date=13 February 2018}} although there are also similarities among different sign languages. Sign languages are independent of spoken languages and follow their own linguistic development. For example, British Sign Language and American Sign Language (ASL) are quite different linguistically and mutually unintelligible. The grammar of sign languages does not usually resemble that of the spoken languages used in the same geographical area. To illustrate, in terms of syntax, ASL shares more in common with spoken Japanese than with English.Nakamura, Karen. (1995). "About American Sign Language." Deaf Resource Library, Yale University. [http://www.deaflibrary.org/asl.html]

As a criterion for distinguishing languages

{{Further|#List of dialects or varieties sometimes considered separate languages}}

Some linguists use mutual intelligibility as the primary linguistic criterion for determining whether two speech varieties represent the same or different languages.{{cite book|last=Gröschel |first=Bernhard| author-link=Bernhard Gröschel |year=2009 |language=de |title=Das Serbokroatische zwischen Linguistik und Politik: mit einer Bibliographie zum postjugoslavischen Sprachenstreit |trans-title=Serbo-Croatian Between Linguistics and Politics: With a Bibliography of the Post-Yugoslav Language Dispute |series=Lincom Studies in Slavic Linguistics; vol 34 |location=Munich |publisher=Lincom Europa |pages=132–136 |isbn=978-3-929075-79-3 |oclc=428012015 |lccn=2009473660 |ol=15295665W}}See e.g. P.H.

Lewandowski, Linguistisches Wörterbuch, Heidelberg/Wiesbaden (5th ed.) 1990, pp. 994–995; L. Campbell, Historical linguistics. An introduction, Edinburgh 1998, p. 165; G.

Crystal, A dictionary of linguistics and phonetics, Oxford (4th ed) 1997, 2003, p. 286.

A primary challenge to this position is that speakers of closely related languages can often communicate with each other effectively if they choose to do so. In the case of transparently cognate languages recognized as distinct such as Spanish and Italian, mutual intelligibility is in principle and in practice not binary (simply yes or no), but occurs in varying degrees, subject to numerous variables specific to individual speakers in the context of the communication.

Classifications may also shift for reasons external to the languages themselves. As an example, in the case of a linear dialect continuum, the central varieties may become extinct, leaving only the varieties at both ends. Consequently, these end varieties may be reclassified as two languages, even though no significant linguistic change has occurred within the two extremes during the extinction of the central varieties.

Furthermore, political and social conventions often override considerations of mutual intelligibility. For example, the varieties of Chinese are often considered a single language, even though there is usually no mutual intelligibility between geographically separated varieties. This is similarly the case among the varieties of Arabic, which also share a single prestige variety in Modern Standard Arabic. In contrast, there is often significant intelligibility between different North Germanic languages. However, because there are various standard forms of the North Germanic languages, they are classified as separate languages.{{cite book|last1=Chambers|first1=J.K.|author-link1=Jack Chambers (linguist)|last2=Trudgill|first2=Peter|author-link2=Peter Trudgill|title=Dialectology|publisher=Cambridge University Press|edition=2nd|year=1998|isbn=978-0-521-59646-6|pages=3–4}}

Within dialect continua

{{Excerpt|Dialect continuum|paragraphs=1,2|bold=no|only=paragraph}}

=North Germanic=

Northern Germanic languages spoken in Scandinavia form a dialect continuum where the two furthermost dialects have almost no mutual intelligibility. As such, spoken Danish and Swedish normally have low mutual intelligibility, but Swedes in the Öresund region (including Malmö and Helsingborg), across the strait from the Danish capital Copenhagen, understand Danish somewhat better, largely due to the proximity of the region to Danish-speaking areas. While Norway was under Danish rule, the Bokmål written standard of Norwegian developed from Dano-Norwegian, a koiné language that evolved among the urban elite in Norwegian cities during the later years of the union. Additionally, Norwegian assimilated a considerable amount of Danish vocabulary as well as traditional Danish expressions.{{cite journal|url=http://www.let.rug.nl/gooskens/pdf/publ_JMMD_2007.pdf |title=The Contribution of Linguistic Factors to the Intelligibility of Closely Related Languages |first=Charlotte|last=Gooskens |journal=Journal of Multilingual and Multicultural Development|volume=28|issue=6|year=2007 |access-date=2010-05-19|doi=10.2167/jmmd511.0|page=445|citeseerx=10.1.1.414.7645 |s2cid=18875358 }} As a consequence, spoken mutual intelligibility is not reciprocal.

=Romance=

Because of the difficulty of imposing boundaries on a continuum, various counts of the Romance languages are given. For example, in The Linguasphere register of the world's languages and speech communities, David Dalby lists 23 languages based on mutual intelligibility:David Dalby, 1999/2000, The Linguasphere register of the world's languages and speech communities.

=South Slavic=

The non-standard vernacular dialects of Serbo-Croatian (Kajkavian, Chakavian and Torlakian) diverge more significantly from all four normative varieties of Serbo-Croatian. Their mutual intelligibility varies greatly between the dialects themselves, with the standard Shtokavian dialect, and with other languages. For example, Torlakian, which is considered a subdialect of Serbian Old Shtokavian, has significant mutual intelligibility with Macedonian and Bulgarian.{{Cite book|url=https://books.google.com/books?id=F7-Bees_VvAC&q=%D0%97%D0%B0+%D0%B4%D0%B8%D0%B0%D0%BB%D0%B5%D0%BA%D1%82%D0%BD%D0%B0%D1%82%D0%B0+%D0%BE%D1%81%D0%BD%D0%BE%D0%B2%D0%B0+%D0%BD%D0%B0+%D0%B5%D0%B4%D0%B8%D0%BD+%D1%80%D1%8A%D0%BA%D0%BE%D0%BF%D0%B8%D1%81+%D0%BE%D1%82+18+%D0%B2%D0%B5%D0%BA,+%D0%B2:+%D0%91%D1%8A%D0%BB%D0%B3%D0%B0%D1%80%D1%81%D0%BA%D0%B8%D1%8F%D1%82+%D0%B5%D0%B7%D0%B8%D0%BA+%D0%BF%D1%80%D0%B5%D0%B7+%D0%A5%D0%A5+%D0%B2%D0%B5%D0%BA&pg=PA280|title=Българският език през ХХ век|first=Василка|last=Радева|date=15 July 2018|publisher=Pensoft Publishers|via=Google Books|isbn=9789546421135}}
