Adjectives for Countable and Uncountable nouns

Adjectives for Countable and Uncountable nouns  

* Some adjectives that describe the quantity of the nouns answer the question ‘How much?’ They cannot be replaced by a number if the nouns are uncountable.

Example:     

1. I want a little rice.

   I want two rice is incorrect.

* However, adjectives of quantity like some, many, much, any, no can be used both as adjectives of quantity as well as number if the nouns are countable.

Example:

1. There are many flowers in the vase.

    There are ten flowers in the vase.
