Since I've already guessed the vowels 'a', 'e', and 'i' (with only 'i' appearing in the word), I'll try a common consonant. 'T' is one of the most frequently used consonants in English words. The pattern '____i_' could potentially be words like "action", "eating", "racing", etc., many of which contain 't'. This gives me a good probability of a correct guess.
