There are a number of factors a word must fulfil for you to lead with it while playing Wordle. For starters, each letter must be distinct. Also, it must have as many vowels as possible in a five-letter word. While doing this will help you determine the answer fast, that will not always the case. However, as long as you get the correct position of one letter, at least, you can consult a word list to find your answer. This post contains a list of five-letter words with O as the last letter. If one of the words you typed in has O in that position and it turns green, then the answer you are looking for is below. You only have to find it.
