verb
Origin
First attested in 1647; borrowed from Medieval Latin culminātus, perfect passive participle of culminō (“to crown”) (see -ate (verb-forming suffix)), from Latin culmen (“peak, highest point”, oblique stem culmin-) + -ō (verb-forming suffix), older form columen (“top, summit”), from Proto-Italic *kolamen, from a Proto-Indo-European base *kol-, *kelH- (“to project, rise; peak, summit, top”), whence also English hill and holm.
