Nowadays, unctuous usually has a negative connotation, but it originated as 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 marked by an artificial gloss of sentimentality. An unctuous individual may mean well, but his or her insincere earnestness can leave an unwelcome residue with others, much like some ointments.
