OK, wondrous words. Every Wednesday, BermudaOnion hosts a meme in which we report on words we've encountered in the past week's reading that we'd never known before. This week, I have two, and they're doozies, especially if you're a grammar freak. I encountered them in The Know-It-All by A.J. Jacobs.
(1) meronym--the middle point between two opposites, e.g. the meronym of "hate" and "love" might be said to be "indifference".
(2) capitonym--a word which is pronounced differently and has a different meaning if the first letter is capitalized, such as "august" and "August."
I'm not sure that knowing those two words will be of great use to me, since I've been a fluent user of the English language since early childhood and got along all right without them, but I do find the concept of the meronym a fascinating one. Perhaps they should teach that one in schools and on Sesame Street!
