In addition, there are diphthongs and triphthongs which are analyzed as a vowel nucleus plus a semivowel ( /j/ or /w/ ) coda because they can not be followed by a final consonant. Source: Internet
Semivowels main Some approximants resemble vowels in acoustic and articulatory properties and the terms semivowel and glide are often used for these non-syllabic vowel-like segments. Source: Internet
Other sequences are considered part of a glide formation process that turns a high vowel into a semivowel (and part of the syllable onset) when followed by another vowel. Source: Internet
Rhyme depends on a vowel and adjacent consonant (which may include the semivowel Short I ). Source: Internet
Similarly, languages often avoid configurations where a semivowel precedes its corresponding vowel. Source: Internet
