much・many・a lot of(たくさんの) Much, Many, A Lot Of
名詞と数 Nouns & Number
迷ったら a lot of。可算にも不可算にも使えて、肯定文で自然です。much(不可算)と many(可算)の主戦場は否定文・疑問文(not much / How many ...?)。肯定の平叙文で much を裸で使うと硬く響く——これがこの3つの実戦配置です。
When in doubt, a lot of: it works with countables and uncountables alike, and it's the natural choice in positive sentences. Much (uncountable) and many (countable) do their best work in negatives and questions — not much, How many …? A bare much in a positive statement sounds stiff. That's the whole deployment map.

Learn the Deployment, Not Just the Rule
教科書は「much =不可算、many =可算」で終わりがちですが、実戦で効くのはもう1軸。肯定文の「たくさん」は a lot of が標準で、much・many は否定・疑問で輝きます: I don't have much time.(あまり時間がない)/ How many people came?(何人来た?)。so much / too much のように強めの言葉が付けば、肯定文でも自然になります。
Textbooks stop at "much for uncountables, many for countables" — but the axis that matters in practice is sentence type. Positive statements default to a lot of, while much and many shine in negatives and questions: I don't have much time. How many people came? Add an intensifier — so much, too much — and they turn natural in positive sentences too.

よくある間違い Common Mistake
I have much homework today.
今日は宿題が多い。(ふつうの会話のつもりで)
I have a lot of homework today.
今日は宿題が多い。
文法的に誤りではありませんが、肯定の平叙文で裸の much は硬く、書き言葉的に響きます。会話は a lot of(またはくだけて lots of)。so much homework(こんなに多い)のように強調が付けば自然です。
Not ungrammatical — just stiff. A bare much in a positive statement sounds bookish; conversation wants a lot of (or the even looser lots of). With an intensifier — so much homework — it turns natural again.
- How much is it? いくらですか? 値段は不可算の量。買い物の最重要フレーズ。 Price is measured, not counted — shopping's key phrase.
- so much / too much こんなにたくさん/多すぎる 強調が付いた much は肯定文でも自然。Thank you so much. もこの仲間。 Intensified much lives happily in positives — Thank you so much included.
- plenty of たっぷりの(足りるほど) 「十分ある」という安心感つきの「たくさん」。We have plenty of time. Abundance with reassurance built in: We have plenty of time.
- lots of どっさりの a lot of のさらにくだけた姉妹形。会話・メッセージ向け。 A lot of's looser sibling — texts and chat.
まとめ Summary
- 肯定文の「たくさん」= a lot of が標準。 Positive "lots" = a lot of.
- much(不可算)・many(可算)は否定・疑問が主戦場。 Much and many work best in negatives and questions.
- so much / too much なら肯定文でも自然。 So much and too much are fine anywhere.
- How much =量・値段、How many =数。 How much asks amount and price; How many asks number.
