What does insincerity mean?
Insincerity describes the quality of speaking or behaving in a way that is not genuine, especially when words and intentions do not match. It can refer to deliberate deceit, such as false friendliness, or to a broader impression that someone’s words lack sincerity. The word is typically used in a critical or formal register, especially in discussion of public statements, political behaviour, apologies, and social interactions. A “note of insincerity” suggests that a particular remark or manner seems false, while “an air of insincerity” describes an overall impression. Insincerity is closely associated with dishonesty and duplicity, but it is more specifically concerned with a lack of genuine feeling or meaning behind outward behaviour. The opposite is sincerity, which implies honesty and genuine feeling.

Where does insincerity come from?
Insincerity is derived from the Latin insincērus, meaning “not sincere,” formed from in-, a prefix indicating negation, and sincērus, “sincere” or “pure.” English borrowed insincere in the early 17th century, and the noun insincerity developed later from that adjective. The family is cognate with sincere and sincerity, all sharing the Latin root sincērus.
