I suspect we have to use the definite article in the following sentence:
I've learned that the meaning of "to abuse" is to use something for bad purpose.
The sentence is constructed by me which means it can contain some grammatical errors. So, what is the right way to use articles here? I've read all of eight clauses in PEU about article but I can't explain that case in a precise way. It seems we have to use
the because I'm talking about the particular meaning, and I myself know what is the meaning. In that way I want to show the listener, apparently has already known about that meaning, despite that may not be mentioned in the conversation erlier.
Am I right? Could you explain?
