Much and many both mean "a large amount", and the choice depends on the noun. Many goes with countable nouns in the plural: many books, many people, many ideas. Much goes with uncountable nouns: much water, much time, much money.
There is a second pattern that learners need just as much. Much is unusual in positive sentences. Positive sentences prefer a lot of or lots of, and much lives mostly in negatives and questions.
This page gives you the count test, the positive-sentence preference, the patterns with too, so and how, and a 20-question drill where each answer names the rule it uses.
The rule
Countable and uncountable: the test
- If you can say one, two, three of the noun, it is countable and takes many: one apple, two apples, many apples.
- If the noun cannot take a number, it is uncountable and takes much: much water, much rice, much information.
- Countable nouns have a plural form: friend, friends. Uncountable nouns do not: advice, information, furniture, money.
- Some nouns change meaning. Hair is uncountable as a mass ("much hair") but countable as individual threads ("many hairs").
Negative sentences and questions
- Much and many are common in negatives: "I do not have much time", "She does not have many friends here."
- They are common in questions: "How much sugar?", "How many eggs?", "Do you get much sleep?"
- In these positions, much and many are neutral and natural.
- The answer to a how much or how many question often uses a lot of or a number: "About a kilo", "Three."
Positive sentences prefer a lot of
- Positive sentences usually take a lot of or lots of with both noun types: "We have a lot of homework", "She has a lot of patience."
- "I have much homework" is grammatically possible but sounds formal or old-fashioned in conversation.
- In formal writing, much and many can appear in positives: "Many students prefer online lessons. Much research supports this."
- A lot of is the safe spoken choice, and it never cares whether the noun is countable.
Too, so and how
- Too many plus a countable plural: "There are too many cars on this road."
- Too much plus an uncountable noun: "I have too much work this week."
- So many and so much work the same way: "I did not expect so many people", "Thank you, that is so much kindness."
- How many asks about a number: "How many students came?" How much asks about an amount or a price: "How much does it cost?"
Amount, number and the of pattern
- Much of and many of appear before the, my, these and other determiners: "Much of the food was cold", "Many of my friends live abroad."
- The amount of takes an uncountable noun: "The amount of traffic is growing."
- The number of takes a countable plural: "The number of visitors is growing."
- Without of, much and many stand directly before the noun: "much traffic", "many visitors".

Questions learners ask
Why is "I have much money" strange but "I do not have much money" fine?
Much is a neutral question and negative word. In a positive statement, English usually wants a stronger or softer phrase: a lot of, lots of, plenty of. "I have much money" is not wrong, but it sounds formal or Russian-influenced to many ears. Use a lot of in speech and much in negatives and questions.
Is "many" wrong in a positive sentence?
No, many is correct in positive sentences, especially in more formal writing: "Many learners enjoy drills." In conversation, a lot of sounds more relaxed: "A lot of learners enjoy drills." Both are correct; the register is the only difference.
How do I choose between "amount" and "number"?
Amount is for uncountable nouns: the amount of water, a large amount of work. Number is for countable plurals: the number of students, a large number of emails. The same countable and uncountable test applies to these two nouns as well.
