Understanding Chinese radicals is a very important part of learning chinese characters. Radicals give you a huge clue as to the meaning of a character.
A common radical is chuo (4) 辶
It represents 'go' or 'walking'. As you can see from the pictograph, it sort of looks like a foot and leg.
Let's have a look at some characters that you'll come across in daily life that use this radical as a component:
过
guo(4). This means to pass, go by, exceed.
送
song(4). This means to see somebody off, deliver, give.
道

进
jin(4). This means enter, go forward.
运

达
