"The teacher likes to play the guitar."
Let's break it down:
* le: This is the indirect object pronoun, meaning "to her" or "to him."
* gusta: This is the third person singular present tense of the verb "gustar," which means "to like."
* tocar: This is the infinitive verb "to play."
* la guitarra: This is the definite article "the" followed by the noun "guitar."
* a maestra: This is the preposition "to" followed by the noun "teacher."
The word order in this sentence is slightly unusual because Spanish uses a different structure for sentences with verbs like "gustar" than English does. In English, we say "The teacher likes to play the guitar," but in Spanish, the order is "The guitar likes to the teacher to play."
The sentence literally translates to "the guitar likes to the teacher to play," but it is understood to mean that the teacher likes to play the guitar.
