object of preposition

[PaulMatthews]

Hi,

About this sentence "The science lab was displayed on ParentsÂ’ Night."

In the book "Parents' Night" is an object of preposition because “Parents'” is written with a capital P. If I changed P to a lowercase to form an adjective, would that violate any grammar rules?

The science lab was displayed on Parents' Night.

The genitive noun phrase "Parents' Night is complement of the preposition "on".

Capitalisation is irrelevant to the analysis, and Parents' is a genitive noun phrase functioning as determiner of "Night".

Correction: diagram is saying "Parents' Night" is an object of preposition. While it’s an object of preposition does that mean "Parents' is still an adjective?

I just told you. Parents' is a genitive noun phrase functioning as determiner of "Night".

And I think it's unreasonable of you to expect us to help you with the RK system. Most people will have no knowledge of it, and those that do usually eschew it.

The genitive noun phrase "Parents' Night is complement of the preposition "on".

Would you please illuminate the difference between objects and complements of prepositions?

No. Emma's is anoun phrase. It functions as a modifier of noun class.

[HeartShape]

No. Emma's is anoun phrase. It functions as a modifier of noun class.

Maybe I am not using an accurate terminology here.

I understand "Emma's class" is a noun phrase and that it modify the word "class" but "Emma's" is an attributive adjective is that not right?

In this particular sentence the attributive adjective modify the noun (class) in this sentence.

[Piscean]

Emma's is not any kind of adjective. It is the possessive form of the proper noun Emma. Its function is to modify the following noun, but that does not change its word class.
