Enspirit \en-SPIR-it\ , verb;
1. To infuse life into; enliven
I know another word for this: coffee
Etymonline.com and the online Oxford English dictionary don't contain this word, but if the etymology is similar to enliven, which is probably is, then it's too boring and obvious to write about anyway.
*Today's word and the first definition were both taken from Dictionary.com's 'Word of the Day' for Monday, November 22
