A digraph is two letters that spell one sound. Digraphs that spell consonant sounds include the letter pairs sh, ch, th, wh, ck, ph, ng. Digraphs that spell vowel sounds include the letter pairs ai, ay, ee, ea, ie, ei, oo, ou. ow, oe, oo, ue, ey, ay, oy, oi, au, aw.
Strictly speaking, we can never see vowels, so that W sitting there on the page is not a vowel and neither is this A. We can only hear vowels. Vowels are sounds. Loosely speaking, the vowel letters A, E, I, O, and U are often called vowels. Y and W may or may not be included among the vowels, depending on the teaching method. The typical sound we make (in English) when we see the letter W is called either a semi-vowel, a semi-consonant, or a glide.
