My question is in the sentance below:

There are three words in the english language that end in -gry.  The
first one is hungry, the second is angry, and if you've listened
carefully i've already told you the third word.

Here you will find several answers to this infuriating teaser, which
is more of a hoax than a puzzle:

Don't bother looking for another common English word that ends in
-gry, after the pattern of hungry and angry. There is no such word.

There are many words in the English language ending in -ance.

'Sentance' is not among them.

Here's another good discussion of the "words that end in -gry" hoax:

The answer is Language. You asked for the third word in the phrase,
"the english language", therefore the answer is, "language".
