How do I use the cue to write sentence with the ver gustar for: Roberto/los libros de misterio/no

Learn the verb gustar as the verb "to be pleasing to" and it will make more sense as to why it is usually used in the 3rd person. One thing IS pleasing to someone and 2 or more things ARE pleasing to someone.

Literally (word for word) you are going to say: "To Robert are not pleasing the books of mystery." OR translated as: "Robert does not like mystery books."

A Roberto no le gustan los libros de misterio.
