ABSTRACT
The spelling of the word has something in common with the object in the real world. We can find a lot of examples in English. For instance, zigzag means that a line or movement that makes sharp angles because it suddenly changes from one direction to another like the letter z which appears twice in the word. The word mountain takes the character of rolling up and down like the shape of letter m, n and u. We also have some abbreviation of words like T-shirt, V-neck, C-wrench, U-turn and so on.
