When do I have to use たくさん and とても?


I don't know when I have to use _totemo_ and _takusan_. They both mean "very",
don't they?




> They both mean "very", don't they?

No, while とても means "very", たくさん does not.

  * たくさん is an adjective, means "a lot of", or "plenty of", and you use it generally for describing noun quantity.

E.g. たくさんのお金{かね} = a lot of money

  * とても is an adverb modifying adjectives.

E.g. とてもうれしい = very glad

Both words are used similarly to their English counterparts.
