I just visited John Langdon's website, of ambigrams fame, since I had seen them mentioned in a few posts here and there on the Board. While I thoroughly enjoy the notion of ambigrams, and admire the work that John has done, I have one, pernickety, pedantic, nit-picking niggle. On the 'philosophy' page, yin and yang are, more than once, referred to as 'complimentary'.

I have spent years correcting letters and booklets in which the word complimentary is used when complementary was meant. Having seen this on John's site as well, I have to ask myself (or any here who might have the answer): has this imprecision proceeded so far as to now be an acceptable part of English, and not one that we should be fighting about any more? Is it no longer a grammatical solecism to talk of two partners complimenting each other, even though they weren't praising each other?
