Can you tell me what words are the infintive phrase and is it a noun, adj or adv? Is it To learn and it's a noun?

To learn to count in three languages is my summer goal.

Yes, you're right -- but you missed the second infinitive phrase: "to count."

"To count" is also a noun because it's the direct object of "learn."
"To learn to count" is an infinitive phrase used as the subject of the sentence. In the phrase," to count" is an infinitive direct object of "to learn".
