We have a highly developed brain that allows us to make use of a very sophisticated language. We learn what words mean from our parents and people around us. This does in no way mean we don't have definitions of the words, because we do. We must. I am using the word "definition" to mean "meaning", because that's a valid use of the word "definition". I can show you what some dictionaries say to prove my point.

That's three dictionaries supporting my use of the word "definition" as "meaning".

What is the meaning that you use for the word "god"?
