Annex is a verb that means to take for oneself.

Coming from late Middle English, our word of the day is derived from the Latin prefix A-D as well as the Latin word nectere (neck TEAR ay) meaning ‘to tie or fasten.’ Often used to describe something a nation does with additional territory, annex may be used in a more informal sense, for example:

My coffee addiction at one point had become such a problem that I confess I would occasionally annex somebody else’s espresso. When I found myself guzzling down a cold cup of coffee I’d swiped from a co-worker, I knew I was deep in the throes of addiction.
