Spanish verb gustar -
to like is a bit complicated.
The verb gustar is not conjugated like the most other
(a ti) te gusta(n)
he, she likes
(a él, a ella)
(a nosotros) nos
(a vosotros) vos
(a ellos) le gusta(n)
The idea here is that the person (I, you, he, she,
we, you, they) is not the subject in those sentences,
but they are indirect objects (dativo). The subject
in these sentences is the object that is liked. According
to the number of this object the conjugation is gusta
(singular) or gustan (plural).
