Brooke got a word-of-the-day calendar last year for Christmas.
Today’s word is
Quadrennial \kwä-‘dre-ne-əl\ adj 1: consisting of or lasting for four years 2: occurring or being done every four years
I’d estimate that I already knew ¾ of the words that came up over the year. Of the remaining ¼ I can remember only a smattering. I suppose if I haven’t had any use for them up to now I’m not likely to need them.
The one new word I can recall a few months later is stridulate. It means (usually referring to insects like grasshoppers or locusts) to make a shrill sound by rubbing the legs, wings, or other parts of the body together. And indeed, it did come up when we were preparing to teach insect life cycles to kindergarteners last October.
