What is the correct way to phrase this idea: "I enjoy to read books?"

The phrase "I enjoy reading books" is correct because it uses the gerund form of the verb "read." In English, when a verb follows "enjoy," it must be in the gerund form, which is the "-ing" form. This construction allows the sentence to express a continuous or ongoing action that brings pleasure.

Using "to read" after "enjoy" is not appropriate, as "to" is the infinitive form of the verb, which does not fit this context. Similarly, the options that use "read" without the gerund form or attempt to phrase the idea unnaturally are grammatically incorrect. Therefore, the correct construction effectively conveys the enjoyment of the activity of reading in a way that aligns with standard English grammar rules.
