Example:How much money have you got?Carla does not have many friends. In positive clauses with so, as or too, we also use much / many. Example:Carla has so many friends.She has as many friends as Sue.Kevin has too much money. In all other positive clauses, however, we prefer expressions like a lot of / lots of. Example:Carla has a lot of / lots of friends.Kevin has a lot of / lots of money. In formal texts, however, much / many are also common in positive clauses. This you will notice for example when you read English news. Countable / Uncountable Nouns In connection with much / many people often speak of countable nouns and uncountable nouns. Countable nouns have a singular and a plural form. In plural, these nouns can be used with a number (that's why they are called 'countable nouns'). Countable nouns take many. Example:100 friends – many friends Uncountable nouns can only be used in singular. These nouns cannot be used with a number (that's why they are called 'uncountable nouns').
