How to break this sentence into clauses and constituents?

Question

I will go at the end of the day?

I am guessing that it’s I will go and then at the end if the day, but how do you break the constituents?

? · Answer

Subject- I
Verb- will go
prepositional phrase modifier- at the end modifying verb
prepositional phrase adjective modifying "end"- of the day

Prepositional phrases can function as adverbs or adjectives.

Complements tell who or what receives the action.
Modifiers tell where, when, how, or in what manner.
