Determiners
Determiners are words like the, an, my, some.
They are grammatically similar. They all come at the beginning of noun
phrases, and usually we cannot use more than one determiner in the same
noun phrase.
Some grammarians do not treat determiners as adjectives, but give them a class of their own.
