Earlier, in my French class, my teacher discussed phonetics and we discussed vowels. My teacher said that aside from a, e, i, o, u, you also consider y as a vowel in French. We tried to compare English and French and I shared with them what I have learned in my elementary classes (my books were written by Americans). I told them that w and y are sometimes considered as vowels in English, but they do not know that. I have only one native English speaking classmate from Canada who agreed, but he is not aware that w is also considered a semi-vowel. There are words that only have y: rhythm, fry, gry, try, fly, etc. I told them that there is at least one word that only has w that serves as a vowel: cwm http://www.m-w.com/dictionary/cwm Is this correct? It seems that this is not generally taught in schools.
