信 xìn

The Chinese character 信 (pronounced xìn) is composed of two
elements - the radical 人 in the altered form of 亻(pronounced
rén meaning person) and the character 言 (yán meaning word; 
to speak).

A person standing by his or her word symbolizes trust, one of
 the meanings of this character. The other meanings are believe
,true, and mail or letter.

The character 信 is classified as an associative compound. While
it is easy to see that a person's word equals trust, this character's
association with mail is less clear. Perhaps we can imagine letters
as a form of communication unique to humankind - people are the
only ones capable of sending words by mail.
