Most uncountable nouns are singular in number. Therefore, we use the singular form of the verb with them.

Uncountable nouns are often treated as countables if we are talking about different kinds of material, liquid etc.
- Most washing powders are not very kind to your hands.

Abstract nouns are usually uncountable. Some abstract nouns can have both countable and uncountable uses. When used with a general meaning, these nouns are usually uncountable. When used with a particular meaning, these nouns are usually countable.

- I couldn’t finish the report because I didn’t get enough time. (uncountable)
Some uncountable nouns are plural. They have no singular forms with the same meaning, and cannot be used with numbers. Common examples are: groceries, arms, remains, goods, customs, clothes, thanks, regards, police etc.

- Have you bought the groceries? (NOT Have you bought the grocery?)
