Doubt About Linking Verbs

Hey guys. How are you? I hope you are doing well!


Anyway, I have a question regarding linking verbs, check it:


According to: Longman English's grammar book:

A complement of subject may be:

- an adjective: Frank is clever.

- a noun: Frank is an architect.

- an adjective + noun: Frank is a clever architect.

- a pronoun: This book is mine.

- an adverb of place or time: The meeting is here. The meeting is at 2.30.

- a prepositional phrase: Alice is like her father.


It says a complement of a subject may be a prepositional phrase; then it means that this sentence is right:


John is the founder and president of this company. His passion is to teach people how to speak english.


So: "Is" is acting as a linking verb, right? Therefore, is "to teach people how to speak english" a complement of the subject? Since it's a prepositional phrase?
