The current state of the word contains a 'a' at the beginning and 'e' at the end. Common letters that might fit in the blank spaces include 'l', 'n', and 's'. Given that the letters 'r', 't', and 'e' have already been guessed (and 'e' is already in the word), I will attempt a guess that is likely to be in line with typical English words. One possible word could be 'agree', so I will guess 'g'.
