If you think an a response could be wrong, then please don't post it. Members come to the Ask a Teacher forum in the belief that the answers they receive will be correct.I'd use "weaker", though it can be wrong.
A few years ago, a student asked me what the difference was between breeze and wind and I said it was largely a matter of collocation. Following on from that, I drew this diagram. I hope it's of use to someone. ;-)
PS My general conclusion was that breezes on the whole were welcoming and winds could be hostile. I was happy with this view for some time, but another student (who came from Las Canarias) pointed out that 'sea breeze' was a collocation; well, maybe he didn't know the collocation, but he was familiar with the use of brisa. So I've been meaning for years to add that, although it doesn't fit in very comfortably with My Scheme!
What would be the antonym for "stronger" in the following sentence, please?
The wind now is stronger than it was a few minutes ago.
Thanks a lot.
