In English, an uncountable noun refers to something (a thing or an idea) that we generally don’t count. Typicall uncountable nouns are liquids, abstract iteas, powders and grains, natural phenomena, and states.
The above graphic shows some of the more common uncountable items that we see in everyday life.
If we want to quantify any of them, we need to add a unit – a slice of bread. a bowl of cereal, etc.
When we use uncountable nouns as the subject of a sentence, the verb must be singular.
For example: Chocolate is sweet. The water is cold.
