In phonology, epenthesis (//; Greek ἐπένθεσις) means the addition of one or more sounds to a word, especially to the interior of a word (at the beginning prothesis and at the end paragoge are commonly used). The word epenthesis comes from epi "in addition to" and en "in" and thesis "putting". Epenthesis may be divided into two types: excrescence or vyanjanabhakti (//; from Sanskrit: व्यञ्जनभक्ति), for the addition of a consonant, and anaptyxis (//; from Greek ἀνάπτυξις) or svarabhakti (//; from Sanskrit) for the addition of a vowel.
Epenthesis arises for a variety of reasons. The phonotactics of a given language may discourage vowels in hiatus or consonant clusters, and a consonant or vowel may be added to make pronunciation easier.
Epenthesis may be represented in writing or be a feature only of the spoken language.
A consonant may be added to separate vowels in hiatus. This is the case with linking and intrusive R.
- drawing → drawring
Bridging consonant clustersEdit
- something → somepthing
- *a-mrotos → ambrotos (see below)
Breaking consonant clustersEdit
A vowel may be placed between consonants to separate them.
- Hamtramck → Hamtramick
While epenthesis most often occurs between two vowels or two consonants, it can also occur between a vowel and a consonant, or at the ends of words. For example, the Japanese prefix ma- (真〜（ま〜）, pure …, complete …) transforms regularly to ma'- (真っ〜（まっ〜）, (gemination of following consonant)) when followed by a consonant, as in masshiro (真っ白（まっしろ）, pure white). The English suffix -t, often found in the form -st, as in amongst (from among + -st), is an example of terminal excrescence.
Historical sound changeEdit
- Latin tremulare > French trembler ("to tremble")
- Old English thunor > English thunder
- French messager, passager > English messenger, passenger
- French message, messager > Portuguese mensagem, mensageiro
- (Reconstructed) Proto-Germanic *sēaną > Old English sāwan, Old Saxon sāian ("to sow")
- (Reconstructed) Proto-Greek *amrotos > Ancient Greek ἄμβροτος ámbrotos ("immortal"; cf. ambrosia)
- Latin homine(m) > homne > homre > Spanish hombre ("man")
- (Reconstructed) Common Slavic *kupjǫ > Old Church Slavonic куплѭ kupljǫ, Russian куплю kuplju ("I will buy")
In French, /t/ is inserted in inverted interrogative phrases between a verb ending in a vowel and a pronoun beginning with a vowel: il a ('he has') > a-t-il ('has he?'). There is no epenthesis from a historical perspective since the a-t is derived from Latin habet (he has), and so the t is the original third-person verb inflection. However it is correct to call it epenthesis when viewed synchronically since the modern basic form of the verb is a and so the psycholinguistic process is therefore the addition of t to the base form.
A similar example is the English indefinite article a, which becomes an before a vowel. In Old English, it was ane in all positions, so a diachronic analysis would see the original n disappearing except if a following vowel required its retention: an > a. However, a synchronic analysis, in keeping with the perception of most native speakers, would (equally correctly) see it as epenthesis: a > an.
In Dutch, whenever the suffix -er (which has several meanings) is attached to a word already ending in -r, an additional -d- is inserted in between. For example, the comparative form of the adjective zoet ("sweet") is zoeter, but the comparative of zuur ("sour") is zuurder and not the expected *zurer. Similarly, the agent noun of verkopen ("to sell") is verkoper ("salesperson"), but the agent noun of uitvoeren ("to perform") is uitvoerder ("performer").
In English, a stop consonant is often added as a transitional sound between the parts of a nasal + fricative sequence:
- English "hamster" // often pronounced with an added "p" sound, GA: [ˈhɛəmpstɚ] or RP: [ˈhampstə]
- English "warmth" // often pronounced with an added "p" sound, GA: [ˈwɔɹmpθ] or RP: [ˈwoːmpθ]
- English "fence" // often pronounced [ˈfɛnts]
- English "else" // by some speakers pronounced [ˈɛɫts]
- Latin reliquiās "remnants, survivors" (accusative plural) > poetic relliquiās
The three short syllables in reliquiās do not fit into dactylic hexameter because of the dactyl's limit of two short syllables so the first syllable is lengthened by adding another l. However, the pronunciation was often not written with double ll, and may have been the normal way of pronouncing a word starting in rel- rather than a poetic modification.
A limited number of words in Japanese use epenthetic consonants to separate vowels. An example is the word harusame (春雨（はるさめ）, spring rain), a compound of haru and ame in which an /s/ is added to separate the final /u/ of haru and the initial /a/ of ame. That is a synchronic analysis. As for a diachronic (historical) analysis, since epenthetic consonants are not used regularly in modern Japanese, the epenthetic /s/ could be from Old Japanese. It is also possible that Old Japanese /ame2/ was once pronounced */same2/; the /s/ would then be not epenthetic but simply an archaic pronunciation. Another example is kosame (小雨（こさめ）, "light rain").
A complex example of epenthesis is massao (真っ青（まっさお）, deep blue, ghastly pale), from ma- (真〜（ま〜）, pure, complete) + ao (青（あお）, blue). It exhibits epenthesis on both morphemes: ma- (真〜（ま〜）) → ma'- (真っ〜（まっ〜）, (gemination of following consonant)) is common (occurring before a consonant), and ao (青（あお）) → sao (青（さお）) occurs only in the example; it can be analyzed as maao → masao (intervocalic) → massao; akin to kirisame (霧雨（きりさめ）, drizzle, light rain) from kiri (霧（きり）, fog, mist) + ame (雨（あめ）, rain).
Epenthesis of a vowel, or anaptyxis (ἀνάπτυξις, "unfolding" in Greek, anaptyctic), is also known by the Sanskrit term svarabhakti. Some accounts distinguish between "intrusive vowels", vowel-like releases of consonants as phonetic detail, and true epenthetic vowels, which are required by the phonotactics of the language and acoustically identical with phonemic vowels.
Historical sound changeEdit
End of wordEdit
Many languages insert a so-called prop vowel at the end of a word to avoid the loss of a non-permitted cluster. The cluster can come about by a change in the phonotactics of the language that no longer permits final clusters. Something similar happened in Sanskrit, with the result that a new vowel -i or -a was added to many words.
Another possibility is a sound change deleting vowels at the end of a word, which is a very common sound change. That may well produce impermissible final clusters. In some cases, the problem was resolved by allowing a resonant to become syllabic or inserting a vowel in the middle of a cluster: Proto-Germanic *akraz "field, acre" > Gothic akrs (syllabic /r/) but Old English æcer (insertion of vowel). In the Gallo-Romance languages, however, a prop vowel was added: MONSTRU > /monstr/ > /monstrə/ (French montre "watch" (clock)).
Middle of wordEdit
Examples are common in many Slavic languages, which had a preference for vowel-final syllables in earlier times. An example of this is the Proto-Slavic form *gordŭ ("town") in which the East Slavic languages inserted an epenthetic vowel to break the cluster -rd-, resulting in *gorodŭ, which became город (gorod) in modern Russian and Ukrainian. The other Slavic languages instead metathesised the vowel and the consonant: *grodŭ (Polish gród, Czech hrad, Serbo-Croatian grad).
Other examples exist in Modern Persian in which former word-initial consonant clusters, which were still extant in Middle Persian, are regularly broken up: Middle Persian brādar > Modern Persian barādar "brother" (a is pronounced [æ]), Middle Persian stūn > Early New Persian sutūn > Modern Persian (Iran) sotūn "column"; modern borrowings are also affected.
Beginning of wordEdit
In the Western Romance languages, a prothetic vowel was inserted at the beginning of any word that began with /s/ and another consonant: Latin spatha "sword" > Spanish/Portuguese espada, Catalan espasa, Old French espede > modern épée (see also espadon, the swordfish).
French has a three level use of initial epenthesis depending on the time of incorporation:
- developing /e/ and dropping /s/ for the earliest: être < stare; école < schola
- developing /e/ and keeping /s/: espèce < species; espace < spatium
- not developing /e/ for the latest: spécial < species; scolaire << schola; spatial << spatium
Epenthesis often breaks up a consonant cluster or vowel sequence that is not permitted by the phonotactics of a language. Regular or semiregular epenthesis commonly occurs in languages with affixes. For example, a reduced vowel /ɪ/ or /ə/ (here abbreviated as /ᵻ/) is inserted before the English plural suffix -/z/ and the past tense suffix -/d/ when the root ends in a similar consonant: glass → glasses /ˈɡlæsᵻz/ or /ˈɡlɑːsᵻz/; bat → batted /ˈbætᵻd/. That is again a synchronic analysis, as the form with the vowel is the original form and the vowel was later often lost.
Vocalic epenthesis typically occurs when words are borrowed from a language that has consonant clusters or syllable codas that are not permitted in the borrowing language.
Languages use various vowels, but schwa is quite common when it is available:
- Hebrew uses a single vowel, the schwa (pronounced /ɛ/ in Israeli Hebrew).
- Japanese generally uses /u/ except after /t/ and /d/, when it uses [o], and after /h/, when it uses an echo vowel. For example, the English word street becomes ストリート /sutoɾiːto/ in Japanese; the Dutch name Gogh becomes ゴッホ /ɡohho/, and the German name becomes Bach, バッハ /bahha/.
- Korean uses [ɯ] except when for a borrowed [ʃ], which takes a following [i] if the consonant is at the end of the word or /ju/ otherwise. For example, English strike becomes 스트라이크 /sɯtʰɯɾaikɯ/, with three epenthetic vowels and a split of English diphthong /ai/ into two syllables.
- Brazilian Portuguese uses /i/, which, in most dialects, triggers palatalization of a preceding /t/ or /d/: "bullying" > [ˈbulĩ ~ bulẽj]; "nerd" > /nɛʁdʒi/; "stress" > /istɾɛsi/ (which became estresse); "McDonald's" > /makidonaudʒis/ ~ [mɛkiˈdõnəwdʑis] with normal vocalization of /l/ to /u/. Most speakers pronounce borrowings with spelling pronunciations, and others try to approximate the nearest equivalents in Portuguese of the phonemes in the original language. Compare "anime" /a'nimi/ with animê /ani'me/ (but the word may also be pronounced /a'nimi/ and written "anime").
- Classical Arabic does not allow clusters at the beginning of a word, and typically uses /i/ to break up such clusters in borrowings: صِرَاط /siraːtˤ/ "street" < Latin strāta.
- Persian also does not allow clusters at the beginning of a word and typically uses /æ/ to break up such clusters in borrowings except between /s/ and /t/, when /o/ is added.
- Spanish does not allow clusters at the beginning of a word with an /s/ in them and adds e- to such words: especia < spice, estándar < standard, estrés < stress.
- Turkish prefixes close vowels to loanwords with initial clusters of alveolar fricatives followed by another consonant: Isparta < Greek Σπάρτη (Spartē), setuskur < set screw, uskumru < Greek σκουμπρί (skúmbri), Üsküdar < Byzantine Greek Σκουτάριον (Skoutarion), istimbot < steamboat, İskoçya < Scotland, istavrit < Greek σταυροειδής (stavridís), İzmir < Greek Σμύρνη (Smyrna). The practice is no longer productive as of late 20th century and a few such words have changed back: spor < ıspor < French sport.
Epenthesis most often occurs within unfamiliar or complex consonant clusters. For example, the name Dwight is commonly pronounced with an epenthetic schwa between the /d/ and the /w/, and many speakers insert a schwa between the /l/ and /t/ of realtor. Irish English and Scottish English are some of the dialects that may insert a schwa between /l/ and /m/ in words like film, under the influence of Celtic languages.
Epenthesis is sometimes used for humorous or childlike effect. For example, the cartoon character Yogi Bear says "pic-a-nic basket" for "picnic basket." Another example is found in the chants of England football fans in which England is usually rendered as [ˈɪŋɡələnd] or the pronunciation of "athlete" as "ath-e-lete". Some apparent occurrences of epenthesis, however, have a separate cause: the pronunciation of nuclear as nucular arises out of analogy with other -cular words (binocular, particular, etc.) rather from than epenthesis.
Certain registers of colloquial Brazilian Portuguese sometimes have [i] between consonant clusters except those with /l/ (atleta), /ɾ/ (prato) or syllable-ending /s/ (produced [ʃ] in a number of dialects, always postalveolar in fluminense and florianopolitano and before voiceless consonants that are not in the end of the word in nordestino, a rare feature in a few others) (pasta) and so words like tsunami, advogado and abdômen are pronounced /tisunami/, /adivoɡadu/ and [abiˈdomẽj]. Some dialects also use [e] for voiced consonant clusters, which is deemed as stereotypical of the lower classes: people who arrived from rural flight or internal migrations in cities such as Rio de Janeiro, Brasília and São Paulo.
In Spanish, it is usual to find epenthetic vowels in sequences of plosive + flap + vowel or labiodental fricative + flap + vowel, normally in a non-emphatic pronunciation. For instance, vinagre has the usual [biˈnaɣɾe] being replaced by [biˈnaɣ(ə)ɾe].
In Finnish, there are two epenthetic vowels and two nativization vowels. One epenthetic vowel is the preceding vowel, found in the illative case ending -(h)*n: maa → maahan, talo → taloon. The second is [e], connecting stems that have historically been consonant stems to their case endings: nim+n → nimen.
In Standard Finnish, consonant clusters may not be broken by epenthetic vowels; foreign words undergo consonant deletion rather than addition of vowels: ranta ("shore") from Germanic strand. However, modern loans may not end in consonants. Even if the word, such as a personal name, is native, a paragogic vowel is needed to connect a consonantal case ending to the word. The vowel is /i/: (Inter)net → netti, or in the case of personal name, Bush + -sta → Bushista "about Bush" (elative case).
Finnish has moraic consonants: l, h and n are of interest. In Standard Finnish, they are slightly intensified before a consonant in a medial cluster: -hj-. Some dialects, like Savo and Ostrobothnian, have epenthesis instead and use the preceding vowel in clusters of type -lC- and -hC-, in Savo also -nh-. (In Finnish linguistics, the phenomenon is often referred to as švaa; the same word can also mean schwa, but it is not a phoneme in Finnish so there is usually no danger of confusion.)
For example, Pohjanmaa "Ostrobothnia" → Pohojammaa, ryhmä → ryhymä, and Savo vanha → vanaha. Ambiguities may result: salmi "strait" vs. salami. (An exception is that in Pohjanmaa, -lj- and -rj- become -li- and -ri-, respectively: kirja → kiria. Also, in a small region in Savo, /e/ is used instead.)
Lojban is a constructed language that seeks logically-oriented grammatic and phonologic structures. It uses a number of consonant clusters on its words, and since it is designed to be as universal as possible, it allows a type of anaptyxis called "buffering" to be used if a speaker finds a cluster difficult or impossible to pronounce. A vowel sound that is nonexistent in Lojban is added between two consonants to make the word easier to pronounce. Despite altering the phonetics of a word, the use of buffering is completely ignored by grammar. Also, the vowel sound used must not be confused with any existing Lojban vowel.
An example of buffering in Lojban: if a speaker finds the cluster [ml] in the word mlatu ("cat") (pronounced ['mlatu]) hard or impossible to pronounce, the vowel [ɐ] can be pronounced between the two consonants, resulting in the form [mɐ'latu]. Nothing changes grammatically, including the spelling and the syllabication of the word.
In sign languageEdit
A type of epenthesis in sign language is known as "movement epenthesis" and occurs, most commonly, during the boundary between signs while the hands move from the posture required by the first sign to that required by the next.
