Recently, Buzzfeed.com ran an article titled,  25 Things You Had No Idea There Were Words For. While you can find the full article here, here are the ones I think writers should not be without:

– Denominalisation: using a word that isn’t a verb as a verb

– Auralize: to mentally create  a sound (the sound equivalent of “visualize”)

– Estival: pertaining to summer (the summer version of “autumnal” or “vernal”)

– Brumal: pertaining to winter

– Yonic: the opposite of phallic

–Susurrus: a whispering or rustling sound

– Sesquipedalian: a word that is polysyllabic -or- someone who uses such words, often while attempting to appear smart.

Honorable mention:

Semantic satiation – a psychological phenomenon in which repetition causes a word or phrase to temporarily lose meaning.
