"We really like playing the guitar."
Translation:Nos gusta mucho tocar la guitarra.
I did "nos le gusta mucho" and it was wrong. I am very confused about when to use "le" and when to omit it.
"en serio nos gusta tocar la guitarra." this is what it gave me for the correct translation after I got it wrong. Can someone please explain this to me?
Gusta is 3rd person singular to agree with tocar, which is really the subject of the sentence. With gustar, you're not really saying we like. The construction is really Playing the guitar is pleasing to us. Nos = to us, and gusta = (it) is pleasing.
Nos gusta estudiar. To study is pleasing to us. = We like to study, studying.
Me gusta el español. Spanish is pleasing to me. = I like Spanish.
Me gustan los perros. Dogs are pleasing to me. = I like dogs.
