The word has the letters 'r', 'a', and 'e' already guessed and it has two blank spaces before 'r' and one after 'e'. The missing letters could potentially be consonants. 'c', 'd', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'o', 'p', 'q', 's', 'u', 'v', 'w', 'x', 'y', 'z' are still available. I will guess 'o' because it fits well with the vowels and it's a common letter that may complete a meaningful word.
