Unsincere vs. Insincere: What's the Difference?

By Aimie Carlson & Janet White || Updated on May 21, 2024
Unsincere refers to lacking sincerity or genuine feelings, while insincere specifically denotes deceitfulness or false display of feelings.

Key Differences

Unsincere refers to the absence of sincerity or genuine emotion. It implies a general lack of heartfelt feeling or honesty in expression. For example, someone might give an unsincere compliment that feels half-hearted or unconvincing. Insincere, on the other hand, denotes a more deliberate falseness. When someone is insincere, they are intentionally being deceitful or pretending to have feelings they do not possess. An insincere apology, for instance, is one given without any real remorse or intention to make amends.
Unsincere actions often come across as indifferent or lacking depth. This can happen unintentionally, where the person might not fully realize their lack of genuine emotion. In contrast, insincere actions are consciously deceptive, aiming to mislead or manipulate others.
The usage of unsincere is less common in English, and it often overlaps with insincere in meaning. However, insincere is the more widely accepted and used term, especially when referring to purposeful deceit or hypocrisy.
While unsincere might be used to describe someone’s lack of genuine interest or engagement, insincere typically involves a calculated effort to feign emotions or intentions for personal gain or to deceive.
