There is an easy way to identify if an infinitive verb is a noun, adjective, or adverb. You can do so by looking at the function of the infinitive verb phrase.
If it modifies or describes a noun or a pronoun, definitely it is acting as an adjective.
Example: I am teaching her a way to improve her writing. (The bolded word is a noun)
I need her to do the cooking.
If it is modifying a verb, it is a verb phrase.
example: He helped to do the cleaning.
Again, if it is answering the question 'Why', it is most likely an adverb phrase.
Example: I came here to see my niece.
If the infinitive is acting like a subject, ojcect, comlement as any other noun would do, it is a noun phrase.
Example: To eat ice cream in a hot day is fun. (Acting as subject)
She loves to dance Salsa. (Acting as object)
His aim was to become a doctor. (Acting as complement)
Hope it helps. Feel free to add a comment or question.
