category error

Well, sort of. Part of speech error, anyway.

Here's the "Sticklers" for today:

Match the word on the left with its meaning on the right.
1. grok	a. faithless
2. esplanade	b. to understand profoundly
3. impuissance	c. a level, open stretch of land
4. perfidy	d. weakness
5. ignominious	e. despicable

Okay, I confess that I've never run into #3 before, but I have met it without its prefix, so it was easy to get (even if I hadn't known the others). But #4 is a noun, and a. is an adjective.

Not a match, Terry!
