Origin

First attested in the 1530s; borrowed from Latin corrōborātus (“strengthened”), perfect passive participle of corrōborō (“to support, corroborate”) (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), from con- (“together”) + rōborō (“to strengthen”), from rōbur, rōboris (“strength”). Regular participial usage of the adjective up until Early Modern English, otherwise archaic.
