Etymology

Origin of unctuous

First recorded in 1350–1400; Middle English, from Medieval Latin ūnctuōsus, equivalent to Latin ūnctu(s) “act of anointing” ( ung(uere) “to smear, anoint” + -tus suffix of verb action) + -ōsus -ous

Explanation

You might know the idea of the adjective unctuous by other words like "oily," "smarmy," or overly "flattering." When a person is unctuous, you can't trust their kindness, because they usually want something in return. Interestingly, unctuous is derived from the Latin unctus which means "anointed with oil," which is where the oily connotation comes from. Unctuous and oily are synonyms that both suggest that someone is trying to butter you up; they're being nice, because they're hoping you'll give them what they want. Talk-show hosts, used-car salesmen, people who want your job: all of these are people we think of (rightly or wrongly) as being unctuous. Being an unctuous jerk, he gave me a gift, hoping I'd give him a record deal.
