信( xìn )

字形：

"信"字由人与言组成，信就是人的话。把一个人的话带给别人，叫捎口信；把人的话写下来邮寄给别人叫寄书信。人的话实事求是叫诚信，有信用。
"信" is made up of two radicals, which respectively indicate people and words. Literally speaking, "信" means people's words. "捎口信 (shāo kǒuxìn)" means sending a message. "寄书信 (jì shūxìn)" means mailing a letter. "诚信(chéng xìn)" means one is reliable and keeps his promise.
