I live in South Africa and I am constantly irritated by the colloquial usage of 'take a decision' instead of what I was taught in school 'make a decision'. Which is correct?
Welcome to the forums.
This is one of those questions that comes up frequently. There seems to be a consensus that "make" is AE and "take" is BrE, but to be honest I cannot see that it is as simple as that.
The British Corpus has more results for "make a decision" than for "take a decision", but if you look at the sources there is a difference in meaning.
It would seem that to make a decision is to weigh up the pros and cons before deciding, and that to take a decision is to act on the selected one.
I shall be interested in other people's views.
