There are some words that do not have plural form as information furniture news etc with all these can we use the like piece of information?

You're right! Words like "information," "furniture," and "news" are considered uncountable nouns. They represent concepts or substances that can't be easily divided into individual items.

Here's why we use "a piece of" or other quantifiers:

* To make them countable: Since these nouns are uncountable, we use phrases like "a piece of information," "a piece of furniture," or "a piece of news" to refer to individual instances of these concepts.

* To express specific quantities: We can also use other quantifiers like "a lot of," "some," "much," or "little" to talk about amounts of these nouns. For example, "a lot of information," "some furniture," "much news."

Here are some examples:

* Instead of: "I have many informations."

* Say: "I have a lot of information."

* Instead of: "There are few furnitures in the room."

* Say: "There are few pieces of furniture in the room."

* Instead of: "I read many news today."

* Say: "I read a lot of news today."

However, there are some exceptions:

* If the noun is used metaphorically or in a specific context: "He has a lot of news to share" (meaning new developments, not individual news articles).

* If the noun refers to different types or categories: "They offer different types of furniture."

Remember, it's best to check the context and meaning of the noun to decide whether to use a quantifier.
