Etymology
The verb is first attested in 1620, the adjective in 1745; borrowed from Latin corrūgātus, perfect passive participle of Latin corrūgō (“to wrinkle, corrugate”) (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), from con- + rūga (“wrinkle, crease”) + -ō (verb-forming suffix). Cognate with Spanish acurrucar (“to snuggle; to curl up due to cold; to huddle”).
