“Instances of heavy rainfall leading to flash flooding are going to become more commonplace due to climate change” – report, 2 August 2021.

I was pulled up short when I read this. Why say “commonplace” when the obvious word here is “common”, meaning “usual”? This is a classic example of someone casually employing a word that sounds similar to the one needed, and in the process subtly changing the meaning of what they are saying. Think about it for a minute: the two words “common” and “commonplace” don’t mean quite the same thing.
