Vowel Teams that (usually) make new sounds (diphthongs) AU/AW, OO/OO, OU/OW, OI/OY
These vowel combinations are (mostly) not short or long, but make completely different vowel sounds. (the last two pairs are formed with mouth positions that change, the definition of diphthong. The first two pairs can be considered to be vowel digraphs – two letters that combine to make one sound.)
Note that AU/AW is a diphthong that makes a Short O sound, and that OW can also make a Long O sound in some words (like know and blow).
