| With words like 'abba' I checked around several other dictionaries to verify, and in some of them (my Webster's, for instance) it doesn't appear as a non-proper noun, while 'aba' does. In any case, yeah, I considered Scrabble words but decided the OED was probably a tad more reliable. Also, if anyone finds a way of making this list that doesn't involve manually checking, that'd be really swell! |
