What does "he makes sense" mean here?
As it turned out, he's not just a loose cannon. He makes sense.
Thanks a lot
There is method in/to his madness.
He's not just a loose cannon - he's a he's a loose battery (of cannon).
Not a very good example, but it makes the point that 'just' requires something stronger to follow what has been selected, not a contrast.
The interesting thing is that I can well imagine myself saying this sentence. It somehow doesn't sound wrong. Or at least it didn't. I guess it's because "just" is so often used just to prolong communication.
"Just" would usually be used in place of "only" but that doesn't really work in that sentence. Had it said "He's not just a loose cannon, he's actually dangerous" or "He's not just a loose cannon, he's also unpredictable and a bit weird" or something similar, the "just" would have made more sense. I didn't notice it either, though.
