Hi there, It's a determiner - Determiners have two functions: a) they show us who or what is being talked about b) they show us how many or how much of something is being talked about In some grammar books you may find that type b determiners are described as adjectives - you can see why, as they tell us more about the noun. However, Cambridge (see below) has a useful way of describing determiners: https://dictionary.cambridge.org/grammar/british-grammar/determiners-the-my-some-this Hope this helps, Helen

I think a grammarian would say its determiner there. But why do you care?
