Let's compare it with 出 - Out (Post 261). Its shell bone script is
Top is a foot, and bottom is a cave people lived in. A foot walks out of the cave is Out, which emphasizes the moment when person walks out, not indicates that he would go far away. Go with a big step means that he is going to somewhere not near by, may need hours or days.
The big seal script of the character is
The small seal script of the character is
The top is still a person walking, the bottom is open cave or house, which may mean that the person opens the door and go out.
The clerical script of the character is
The top lines are straight, difficult to see a person walking. The bottom is become a triangle with a top open, which is similar to the small seal script.
Its Pinyin is Qu4.
I mentioned 出 - Out, which is some similar to 去 - Go. As time past, people often use 出去 together as a compound word, which means Go Out, specifically used in the time when people are inside to go outside.
