Difference between "suyo" and "su/sus"?
What is the difference between the usage of these two words? I know that "suyo" means "yours" but it means "his/her/your/their" too just as "su/sus"?
So when do we these two words?
Suyo is a possessive pronoun. Su is a possessive adjective.
An adjective describes a noun, and a pronoun takes the place of a person.
Su casa es verde= His/her/your house is green.
La casa verde es suyo= The green house is his/hers/yours
A rule of thumb is mio/tuyo/suyo usually comes after the noun, while mi/tu/su usually comes before.
Yes, "suyo" means his, hers, yours (usted/ustedes), and theirs, just like "su/sus" does.
As a rule of thumb, if you are naming the object, you use the "su/sus" and if the object is not named, you use "suyo".
¿Es su abrigo? (Is this your coat?)
No, no es mío, es syuo. (No, it's not mine, it's his)
