Yes, I concede it's a bit of a bugbear - apologies for the negativity. The idea that not spending the requisite minute or so to look up meaning and usage of a new word is acceptable behaviour of adults seems depressingly defeatist. We don't consider this an acceptable attitude during a child's dozen or more years of formal education, and realistically most adults have easy & rapid access to authoritative sources. That our languages should then be (re)defined by these torpid users -- well that's just a horrible deal.
