Character refers to the indefinable qualities that make up a person's unique personality, especially those traits that are positive. For example, an honest person is said to have "good character." In this sense, character may be interchangeable with reputation.Character is also intimately related with one's outlook on life. For example, one might have a conservative character, identified by a strong sense of self, by self reliance and abhorrence of deceit, or, conversely, a liberal character.
Character can also refer to a letter in the alphabet or a number, such as a character on a keyboard.
