1. what is the difference between suyo and tuyo? since they mean the same thing "yours"? How do you use it? What if you wanna say "his is better than yours"?(suyo es mejor que suyo?)
2. OMG...why suyo has so many meanings?Yours,his,hers,etc etc.This is so unlike to English and Chinese languages. Do spanish speaking people have to find out which meaning suyo indicates based on the context every time? Don't they find it complicated?
The problem with "suyo" (and all the 3rd person pronouns) is that they can also refer to the 2nd person (because of the pronoun "usted", as kokoyaya
Actually, you could say "suyo es mejor que suyo", but it would be ambiguous. The fact that the pronoun "suyo" can refer both to "his/hers/theirs" and "yours" may cause many ambiguity in Spanish.
Notice, for example, the following ambiguity:
"El carro es suyo."
This could mean "the car is his", "the car is hers", "the car is theirs" or "the car is yours".
To prevent this ambiguity, instead of using "suyo", you could write:
"El carro es de él." ("the car is his", non-ambiguous).
"El carro es de ella." ("the car is hers", non-ambiguous).
"El carro es de ellos." ("the car is theirs", non-ambiguous).
"El carro es de usted." ("the car is yours", non-ambiguous).
The above examples were just to show that, many times, the use of certain pronouns may cause ambiguity.
