Today's words

As I was keeping up on other things over the weekend, I completely missed a couple new words, plus the one for today:

nocuous \NAH-kyuh-wus\ - harmful

Well, of course there has to be an opposite of innocuous!

rowel \ROWL\ - 1. to goad with or as if with a pointed disk at the end of a spur  2. vex, trouble

I might have known the first definition at one time, and from it the second makes sense. Would have pronounced it as two syllables, though.

corn salad \KORN-SAL-ud\ - any of several herbs (genus Valerianella) of the valerian family; especially : a low European herb (V. locusta syn. V. olitoria) that is widely cultivated for its leaves used in salads and as a potherb

If I ever saw this, I surely thought the user was talking about a salad with a main ingredient of maize.
