Did You Know?
Nowadays, "unctuous" has a negative connotation, but it originated in a term describing a positive act, that of healing. The word comes from the Latin verb unguere ("to anoint"), a root that also gave rise to the words "unguent" ("a soothing or healing salve") and "ointment." The oily nature of ointments may have led to the application of "unctuous" to describe things that are afflicted with an artificial gloss of sentimentality. An unctuous individual may mean well, but his or her insincere earnestness may leave an unwelcome residue with others, much like some ointments.
Origin and Etymology of unctuous
