palliate

The verb was inherited from Middle English palliaten (“To palliate (a disease), relieve the symptoms of (a patient); to extenuate (an offense); to conceal, hide”), the adjective and participle from its participle palliat(e); further borrowed either from Middle French pallier or directly from Latin palliātus, perfect passive participle of palliō (“to cover with a cloak”)), from pallium (“a cloak”), see -ate (verb-forming suffix) and -ate (adjective-forming suffix).
