Determiners - SS1 English Past Questions and Answers - page 1

Determiners are important in a sentence because they provide information about the noun that they modify. This information can include the number, quantity, or identity of the noun. Determiners can also be used to make sentences more specific and clear. 

To identify a determiner in a sentence, look for a word that comes before a noun and provides information about it. For example, in the sentence "The cat sat on the mat," the word "the" is a determiner because it comes before the noun "cat" and provides information about it. The determiner "the" tells us that the cat in the sentence is a specific cat, not just any cat.
