Librate is an adjective that means to poise or remained balanced.
The Latin word for poise or balance is libramen (lee BRAHM en) where our word of the day comes from. It may be used in a scientific sense to refer, for example, to molecule holding in place by oscillating. Or it may be used in a more every day sense to simply mean ‘balance.’
It’s lovely to see those birds librate on the telephone wire. I’m amazed at their ability to stay in place without falling.
