我( wǒ )
字形：
“我”字的古体，是一种长柄、三齿兵器的象形。在原始公有制度下，这种兵器可能最早固定地属于个人使用，于是这种兵器的象形，就有了“我”，“我的”意思。
The Chinese pictogram for "I" represents a weapon with long handles and three tooth-like things on the top. In the primitive society, this type of weapon was appointed to and belonged to individuals, and thus this weapon carried the connotation of "I" and "my".
