A secondary meaning of crossgrained is
"Perverse; untractable; contrary; difficult to deal with. (eg) She was none of your crossgrained, termagant, scolding jades. - Arbuthnot."
What is the etymology of this usage, and when was the word first so used?
Note, crossgrained most commonly means "Having the grain or fibers run diagonally, or more or less transversely and irregularly, so as to interfere with splitting or planing". That this is by far the most-common usage of the word can be seen via examples for crossgrained and cross grained from ngrams. ngrams also shows that the form crossgrained is used far more often than either of the forms cross grained or cross-grained; but neither wiktionary nor etymonline includes crossgrained.
