genitive cases

[takethebest]

Hi everyone,

I am studying different aspects of the genitive in English.
And I came accross this exemple " a moment's pondering" which is shown in the genitive list. So I am wondering what place does pondering have here, and also is it considered a determinative genitive?

I want to state that N1 is <moment> and N2 is <pondering>, but does <pondering> act as an adj/adv/present participle...?

It is just a little bit confusing,
I hope you can help

Ps: I am not a native.

"A moment's" is indeed a determinative phrase, its noun being in the possessive (a.k.a. genitive) case. Its referent "pondering" is a gerund.
