Triphthong

In phonetics, a triphthong (from Greek , lit. 'with three sounds' or 'with three tones') is a monosyllabic vowel combination involving a quick but smooth movement of the articulator from one vowel quality to another that passes over a third. While "pure" vowels, or monophthongs, are said to have one target articulator position, diphthongs have two and triphthongs three.

Triphthongs are not to be confused with disyllabic sequences of a diphthong followed by a monophthong, as in German Feuer 'fire', where the final vowel is longer than those found in triphthongs.

Examples
Triphthongs that feature close elements typically analyzed as and  in phonology are not listed. For instance, the Polish word łój 'tallow' is typically analyzed as  - a sequence of a consonant followed by a vowel and another consonant. This is because the palatal approximant is resyllabified in some inflected forms, such as łojami (instr. pl.), and also because  occurs word-finally after a consonant just like  does (compare przemysł  'industry' with Przemyśl  'Przemyśl'), which means that both of them behave more like consonants than vowels.

On the other hand, are not treated as phonetic consonants when they arise from vocalization of,  or  as they do not share almost all of their features with those three.

Bernese German
Bernese German has the following triphthongs:
 * as in Gieu 'boy'
 * as in Gfüeu 'feeling'
 * as in Schueu 'school'

They have arisen due to the vocalization of in the syllable coda; compare the last two with Standard German Gefühl  and Schule, the last one with a schwa not present in the Bernese word.

Danish
Danish has the following triphthongs:
 * as in færge 'ferry'
 * as in hvirvle 'to whirl'
 * as in Børge, a given name
 * as in spurv 'sparrow'

English
In British Received Pronunciation, and most other non-rhotic (r-dropping) varieties of English, monosyllabic triphthongs with R are optionally distinguished from sequences with disyllabic realizations:
 * as in: flour (compare with disyllabic "flower" )
 * as in: byre (compare with disyllabic "buyer" )
 * as in: coir (compare with disyllabic "coyer" ), loir (compare with disyllabic "lawyer" )

As and  become  and  respectively before, most instances of  and  are words with the suffix "-er", such as player and lower. Other instances are loanwords, such as boa.

are sometimes written as ⟨awə, ajə, ɔjə⟩, or similarly. On Wikipedia, they are not considered to feature the approximants and, following the analysis adopted by the majority of sources.

Second segment is the nucleus
Spanish:
 * as in buey 'ox'
 * as in Uruguay 'Uruguay'
 * as in cambiáis 'you [informal plural] change'
 * as in cambiéis 'that you [informal plural] may change'

The last two are mostly restricted to European Spanish. In Latin American Spanish (which has no distinct vosotros form), the corresponding words are cambian and cambien, with a rising-opening diphthong followed by a nasal stop and initial, rather than final stress. In phonology, are analyzed as a monosyllabic sequence of three vowels:. In Help:IPA/Spanish, those triphthongs are transcribed ⟨wej, waj, jaj, jej⟩:, , ,
