Determiners and quantifiers

Determiners and quantifiers are words we use in front of nouns. We use determiners to identify things (this book, my sister) and we use quantifiers to say how much or how many (a few people, a lot of problems).

Read clear grammar explanations and example sentences to help you understand how determiners and quantifiers are used. Then, put your grammar knowledge into practice by doing the exercises.

Hello there,

Hope all is well.

I came across the terms "Definite Determiner" and "Indefinite Determiner", I can't figure out what that is. I found a few questions in a book where they ask to identify whether the words in quotes are Definite or Indefinite. Do they just refer to the usage of definite (the) and indefinite (a, an) articles?

1. Internet radio stations have added "a new dimension".
2. ...which could affect "the speed of other activities" that you indulge in online.
3. ...especially those who love music from all over "the world".

Appreciate the help :-)

Hello AllyEnglish,

Yes, it sounds to me as if they mean what you suggest.

Best wishes,

Thanks so much


Please, why is the definite article in the phrase "the impossible" used? Since an article cannot be used with an adjective unless it's used to represent a class just as in "the poor"?

Hello Abdulsalam,

I'm afraid I'd need to know the context to be able to answer that. 

It's true that we don't generally use an article before an adjective in this way, except when speaking about nationalities or well-known groups, e.g. 'the poor', 'the elderly', etc.

All the best,

Hello Sir,
I want to know the difference between the two sentences below. It get me somewhat confused if the article "a" should be added. Which is correct?

1. They considered her heroine.
2. They considered her a heroine.



Hello Progress,

1 is not correct and 2 is correct. Being a heroine is not exactly a profession, but we use 'a' before a person's profession (for example, 'I am a teacher', 'She is a pastor', etc.).

All the best

Thanks Sir for the reply.

Is it correct to replace "the" with "a "before 'sum' in the following sentence?

" She was paid the sum of Rupees 50,000 for that book on Indian history"

Kindly explain.

Hello p t balagopal,

Yes, you can use either a or the here. When we give a concrete figure in a context like this we can use either the definite or indefinite article.
