This week’s word is not one of my favourites. Correction, I like to haul this word out like a good nerd. But its never fun to be associated with someone who is:
Capricious |kəˈpriSHəs, -ˈprē-| (adjective)
Given to sudden and unaccountable changes of mood or behavior: a capricious and often brutal administration | a capricious climate. In other words, you never know what they’re gonna do.
ORIGIN early 17th cent.: from French capricieux, from Italian (see capriccioso).
Definition credit goes to the New Oxford American Dictionary (aka the Dictionary on my Macbook).
