'Much' and 'Many'

1. 'Much' and 'many' suggest a large quantity ('a lot of')
2. 'Much' precedes uncountable nouns:
1. I don't have much time, I must leave now
3. 'Many' precedes countable nouns:
1. We have many friends in Australia
4. When asking about quantities, we use 'how much' with uncountable nouns and 'how many' with countable nouns:
1. How much sugar would you like with your coffee?
2. How many dogs does John have?
5. Irregular plural nouns are all countable and therefore they have to be used with 'many'. Some common plural nouns are:
1. People, men, women, children, feet, teeth, dice, mice
6. 'Information', 'luggage' (or 'baggage'), and 'equipment' are uncountable nouns and therefore they have to be used with 'much':
1. How much luggage/baggage did you bring?
2. How much information did they give you?
3. How much equipment do you need for the job?
7. 'Much' and 'many' are often preceded by 'so', 'too', or 'as' to indicate very large quantities or for making comparisons:
1. He has so many friends that he couldn't invite them all to his birthday party (very large quantity)
2. You've put too much sugar in my coffee! (very large quantity)
3. He doesn't have as much money as she does (comparison)
