Is “entitled” a verb or adjective or both in “She is entitled…”?

Question

She is entitled to all luxuries in her life.

What is the voice of the sentence? If it is passive, which word is the main verb in the sentence?

In this sentence the word "entitled" is used as adjective, without the adjective the sentence has the complete meaning. If so without "entitled" the above sentence's meaning should be complete but it is not the case. Is the word "entitled" also a verb?

Answer 1

Study the sentence. She is grateful to her friends. If the adjective grateful is removed from the sentence it will become meaningless. In the same manner entitled is used as an adjective.
