     I guess this was meant to be a trick question.  According to the site that 6dogs 4us referred us to, there are dozens of words (now obsolete) ending in "gry".  So the correct phrasing iof this trick question is the following: Think of words ending in "-gry". "Angry" and "hungry" are two of them. There are only three words in "the English language." What is the third word? The word is something that everyone uses every day. If you have listened carefully, I have already told you what it is.

The answer is language.

You didn't phrase the question right.....It should be "Two of the words in the English dictionary that end with gry are hungry and angry...what is the third one?".....Your question makes it look like there is a trick answer....

dictionary because the third word in The English Language
