Answer:
something (very convoluted answer).
Step-by-step explanation:
It helps if you go word by word.
Cherie : Proper noun
will give: verb
something: what is this? Let's just leave it for a second.
special: this is an adjective, but what does it modify?
to: a preposition beginning of a phrase
her: a possessive pronoun
cousin: what's being possessed. and it's a noun.
So we have to go back to something. It's a pronoun or an adverb. It's not an adverb because it would have to modify special. What kind of a special is something? So it must be an indefinite pronoun.
We are not sure what something is, but it takes the place of the noun that Cherie is going to give her cousin.
