What does sincere mean?
Sincere describes a person, statement, or feeling that is truthful, earnest, and free from pretence or exaggeration. Someone may be sincere when they express an apology, offer thanks, describe a concern, or give a compliment in a genuine and heartfelt way. The word can also refer to an expression or intention that is offered without disguise, although using it does not by itself prove that the feeling behind the words is genuine. Sincere is often stronger and more approving than simply truthful: a sincere apology, for instance, implies that it is offered honestly and takes responsibility rather than merely using polite formula. In everyday use, “sincerely” is also a standard and warm form of closing a letter. Because sincere suggests both honesty and emotional directness, it is commonly associated with good intentions, although a sincerely expressed sentiment can still be mistaken.
