I had always understood the term "one of a kind" to be the same as "one of a type". If a person was "one of a kind" the implication was that there were a number of people of that type and he/she happened to be one of them.
When I heard some time ago on TV of the death of Norman Wisdom, the item ended with the words "Whatever you thought of him, there can be no doubt that he was one of a kind". But what they meant to say surely was that he was unique, not just one of a kind.
And I have heard this (to my mind) incorrect usage quite a number of times recently. Has anyone else noticed this? Should we care?
Of course I may be showing myself up here as one of a kind (pedant).
