Letter R to letter E. In chinese letter R is written as 呀 and to say it in english: ‘are’.
If you reverse the letter R, it will be like ‘я’. Does 呀 look like ‘oя’? So you learned one chinese character 呀! which expresses a feeling, a surprise!
The chinese character 衣 sound exactly like the letter E. In english, may be ‘yee’. As ‘e’ can sound differently like ‘er’ or ‘ae’. So ‘ee’ may be the way to express the sound of the letter E. 衣 is cloth. Now you learn two chinese characters. Does 衣 look like E?
