NOUNS WITH EXCEPTIONAL GENDERS

FRENCH
To each example we insert the adjective "good" so that the definite article will not replace the vowel with an apostrophe.
-age (we expect masculine: le _____age ) -ée (we expect feminine: la _____ée ) -son (we expect feminine: la _____son ) -ure (we expect feminine: la _____ure ) -oire (we expect feminine: la _____oire )

All chemistry terms that end with -ure are masculine.

Our goal here was to find common words. Other words were listed in the references I reviewed for things like ivory and tuning fork--words you probably will not need any time soon. For some words that corresponded to common English words, I found that when I put them into my computer translator program, it gave me other words, and it didn't give me the word in the reference, so I decided that the word in the reference must be obscure.
