Yesterday I saw "dead man walking" Clegg on the box trying to justify the economic crimes to which he is party. He talked of "taking" difficult decisions. I've heard a lot of decision taking on the news lately. Didn't we used to MAKE decisions? I'm sure we did. I was thinking it might be one of those americanisms that are infiltrated into our speech by media wallahs, but then I remembered the Three Degrees and their song -

"Yes, this is the year
to make your decision."
(I like that record)

Anyway, Yanks do a lot of calling these days: "Good call", "It's your call", etc.
So maybe decision taking is as valid as decision making. It's just that I've only been hearing it in the last year or so.
