Best practice
When using "unctuous" to describe a person, ensure that the context clearly indicates whether you are referring to their insincere behavior or a perceived moral failing. Otherwise, your readers may misinterpret your intended meaning.
Common error
Avoid confusing "unctuous", which means excessively flattering or oily, with "unction", which refers to the act of anointing with oil, especially as a religious rite. Using "unction" when you mean "unctuous" will result in an error.
