A rising triphthong begins with a semivowel [j] or [w]. In English rising triphthongs are normally analyzed as sequences of two phonemes. There are many rising triphthongs in English, as /j/ and /w/ can combine with many diphthongs.
- /jəʊ/: yoga
- /jɪə/: year
- /jʊə/: cure
- /waɪ/: quite
- /waʊ/: wow
- /weə/: square
- /weɪ/: way
- /wəʊ/: quote
- /wɪə/: weird
Linguist John Wells thinks there are no triphthongs in English, and in all cases there are two syllables. This means that the difference between liar /ˈlaɪ.ər/ and lyre /laɪər/ does not exist: many people agree that these two words are homophones. Note that Wells considers cure /kjʊər/ to be a monosyllable, but not a triphthong, because /j/ is a semivowel and not a vowel.
