                                These are composed of two vowels that when blended make one sound: ai, ea, ee, oa.  The saying is “when two vowels go walking the first does the talking – and says its own long name (e.g., bait, treat, beet, boat, respectively). BUT ea also makes the short sound of e (e.g., thread, dread, sweater).
                                What are vowel digraphs?
