Today's words

First, several from the Dictionary Devil puzzle:

aplite /ˈa-ˌplīt/ - a fine-grained light-colored granite consisting almost entirely of quartz and feldspar

A word that should always be taken for granite.

pluvial /ˈplü-vē-əl/ - 1a.  of or relating to rain  b.  characterized by abundant rain  2. of a geologic change : resulting from the action of rain

We've had a quite pluvial May in these parts. This word continues to chase me to the online dictionary whenever I encounter it.

petrel /ˈpe-trəl, ˈpē-/ - any of numerous seabirds (especially families Procellariidae and Hydrobatidae); especially :  one of the smaller long-winged birds that fly far from land — compare storm petrel

Based on its etymology, I'm guessing that the second pronunciation is a variation based on the word's current spelling.

limpid /ˈlim-pəd/ - 1a. marked by transparency (see transparent 1) :  pellucid  - limpid streams
b.  clear and simple in style - limpid prose  2.  absolutely serene and untroubled

Funny thing: the closest I've been to the second definition in a very long time was the night I thought I might be dying. 

Finally, a new WOTD:

inanition /in-uh-NISH-un/ - 1. the exhausted condition that results from lack of food and water
2. the absence or loss of social, moral, or intellectual vitality or vigor

I am certain that I've encountered this word before, and known what it meant from context. Perhaps the relationship with inane will help me to recall it should I run into it again, but I'm concerned it will just throw me off.
