Use of ‘parameter’
I see that I'm in a long-term edit war with Vladimir Nesov over this. For citation, see pretty much any result of a search on the two words. Although this new meaning of ‘parameter’ will probably become almost fully accepted by the end of the century (if not much sooner), it began as an error and it certainly grates on me. That said, ‘perimeter’ is not always the best substitute, and I have now used ‘limit’.
