Nouns can be converted from uncountable to countable, and vice versa

The uncountable form always has a more generalized meaning, whereas the countable form has a more specified meaning Changing uncountable nouns into countable form usually requires some kind of container or package or unit measure: water → a glass of water, advice → a piece of advice, Life is hard → He had a hard life. On the other hand, changing countable nouns into uncountable forms usually requires changing them into a more abstract or generalized form: a chair → furniture, a book → literature, printed matter, a fact →-> knowledge, data

Many nouns meaning materials can become countable nouns when they are used to refer to an amount of something in a container:

a coffee, a beer, a whisky

beer rum

brandy sherry

coffee sugar

Coke vodka

gin whisky

lager yoghurt

Some of these words are used in restaurants and cafes but not in people's homes. For example, you might ask for "two teas" in a cafe, but someone in their own home would probably say, "Would you like some tea:" or "Would you like a cup of tea:" rather than Would you like а tea? "

Uncountable nouns can also be converted into countable nouns when "a type of" or "a variety of is meant

a local cheese, a very fine jam

beer metal

brandy paint

cheese perfume

coffee sauce

detergent soup
