The pattern "__a_t" suggests a 4-letter word with "a" in the 3rd position and "t" at the end. "h" is a common consonant that could form "what" or "chat", both common 4-letter words matching this pattern. Since we've only guessed vowel "a" and "e" (which was wrong) and consonant "t", trying another common consonant like "h" has good odds of success.
