As this is an English Learners space, it's important that idiom is explored when trying to ascertain real world usage.
Some here have of course already pointed this out very well. I dub thee Members of the Grand Order of Practical Applicationists.
Let's start by agreeing that the does not = enough from the point of view of any accepted dictionary definition.
Let's now explore how the use of the can have an implication of enough, so that we can in fact say yes, the can sometimes mean enough in the context of an utterance or written sentence.
I'm no expert, but I think that when we are exploring idiom, we can either relax or ignore "the rules", such that explanations based on articles and clauses don't necessarily aid a learner who is trying to understand how English is actually spoken and used by living breathing humans.
So here goes, let's take a line from a Guy Ritchie movie (Snatch, 2000):
what? you wanna see if I've got the minerals?
Once we decode this from the Cockney Rhyming Slang (minerals = stones = balls), we get:
what? you wanna see if I have the balls?
Ref: cockney dictionary: minerals
Now let's see an explanation of what this actually means, as explained by one user (Annsyre) on another forum (quoting I think the actor who played in the movie):
"It would seem that Snatch is a very popular film and I get at least 3 letters a week asking what "minerals" are. They are, simply, testicles. Slang for testicles is "stones", so when he says "You haven't got the minerals" he means "You haven't got the stones". The implication is that he lacks the nerve, that he isn't man enough." (bold mine)
Note Annsyre's use of the important word "implication" in his explanation. (implication: the conclusion that can be drawn from something although it is not explicitly stated.)
So, for people learning English, the answer to the original question is yes, the can sometimes mean (or perhaps more accurately, imply) enough, and like learning any language, when it comes to learning idiomatic usage it helps to simply be aware of nuance which is usually heavily context driven. Meaning is not always explicitly stated, and that is of course amongst the hardest things about learning new languages.
Hope this helps at least one person.
