Semivowel
In phonetics and phonology, a semivowel or glide is a sound phonetically similar to a vowel sound but functions as the syllable boundary, rather than as the nucleus of a syllable. Examples of semivowels in English are the consonants y and w, in yes and west. Written /jw/ in IPA, y and w are near to the vowels ee and oo in seen and moon, written /iːuː/ in IPA.
