Etymology

Inherited from Middle English deliberat(e), borrowed from Latin dēlīberātus, perfect passive participle of dēlīberō (“to consider, weigh well”) (see -ate (adjective-forming suffix) and -ate (verb-forming suffix)), from dē- + līberō / lībrō (“to weigh”)), from libera / libra (“a balance”); see librate. Doublet of deliber.
