2- DETERMINERS

Determiners are modifiers of nouns. There are some determiners that occur only with singular count nouns like a, one, another and many determiners that occur only with plural count nous: these, those, many, both, two, three, and so on. A few determiners occur only with uncountable nouns: much, (a) little; and some determiners occur with either plural nous or uncountable nouns: some, all, no, other.

Determiners include articles, quantifiers, numbers, possessive adjectives (a. g. my, your, their) and demonstrative adjective ( this, that, these, those ).
