I heard that each character contains its own meaning, which bugs me because there are thousands of them knowing that I saw several kanji that seem to carry the same meanings... O.o
Not many characters hold exactly the same meaning - however they have the same English definition. For example 明 and 亮 are both talking about different types of bright. You cannot use them interchangeably.
It seems hard - but just start :) .... After a while, you will just suddenly know the meaning of so many characters!
Like see and watch in English, these words have their own usage.
Just keep learning and practicing, and it will come naturally.
Hope my answer could help. Btw, I'm learning Spanish, add me on Skype if you are interested.
I think you buy a dictionary is better, the Modern Chinese Dictionary or Ci Hai, encountered do not understand can read, learning Chinese will be much simpler. If you need the answer to tell me, I will teach you, of course, line can also be on the exchange.
