Quantifiers determiners are an important part of English grammar. They are used to express the quantity or amount of something. In simple terms, they help us answer questions like "How much?" or "How many?"

There are two types of quantifiers determiners: definite and indefinite. Definite quantifiers determiners refer to a specific quantity, while indefinite quantifiers determiners refer to an unspecified quantity.

Some common examples of definite quantifiers determiners are "all," "both," "every," and "each." For instance, "All students must attend the meeting" means that every student is required to attend. In Hindi, we can say "सभी छात्रों को बैठक में शामिल होना चाहिए."

On the other hand, indefinite quantifiers determiners include words like "some," "any," "many," and "few." For example, "I have some books" means that I have an unspecified number of books. In Hindi, we can say "मेरे पास कुछ किताबें हैं."

It is important to note that quantifiers determiners should agree with the noun they modify in terms of singular or plural form. For instance, we say "many books" but "much water." In Hindi, we can say "बहुत सारी किताबें" and "बहुत पानी" respectively.

One common mistake is using quantifiers determiners with uncountable nouns. For example, we should say "a little water" instead of "a few water." In Hindi, we can say "थोड़ा पानी" instead of "कुछ पानी."

In conclusion, quantifiers determiners are essential in English grammar to express the quantity or amount of something. By understanding their usage and avoiding common mistakes, we can improve our English language skills.
