What does gustan mean in English?

"Gustan" in Spanish means "they please" or "they like". It is the third person plural form of the verb "gustar".

Example:

* A mí me gustan las flores. (I like flowers.)

* ¿A ustedes les gustan los perros? (Do you like dogs?)

Note: The verb "gustar" is used differently in Spanish than in English. In English, we would say "I like flowers" or "Do you like dogs?". However, in Spanish, the verb "gustar" means "to please", and the object of the verb is the thing that is liked.
