unctuous

What does "unctuous" mean?
Unctuous describes someone who is excessively or ingratiatingly flattering, often in a way that feels oily, insincere, or "slick." Imagine a salesperson who is so eager to please and overly complimentary that their charm starts to feel greasy or manipulative rather than genuine. The word originates from the literal meaning of "oily" or "greasy," which helps explain why it carries a negative connotation of someone trying too hard to smooth things over. It is typically used in formal writing or critical speech to characterize people who are sycophantic or oily in their mannerisms.
