This is the 1694th most frequent Catalan word.
teus
"Teus" means "your" (plural, masculine) in English.
In this sentence, 'teus' is a possessive pronoun used to indicate that the books belong to the person being addressed.
Els teus llibres estan sobre la taula.
Your books are on the table.
Here, 'teus' expresses possession and modifies the noun 'amics' to specify the ownership of the friends.
He trobat uns amics teus al parc.
I found some of your friends in the park.
In this example, 'teus' again acts as a possessive pronoun qualifying the noun 'preferits' to convey that the favorites belong to the listener.
