How to say "generously" in Japanese

• たっぷりJLPT N3approx.Common
  adverb (with と), na-adjective, suffixCovers the general sense of doing something plentifully or amply, e.g. adding a generous amount. It suggests abundance and sufficiency rather than forceful movement, and works in many everyday contexts.
  教授きょうじゅの話はなしはユーモアたっぷりだった。↗

  The professor's speech was full of humor.
• じゃぶじゃぶCommon
  adverb (with と)Matches 'generously' only in the sense of pouring sauce or other liquid copiously and vigorously. It is a mimetic word evoking splashing or gushing, so it is not the word for generous giving in general.

Use 「たっぷり」 for giving or adding something in plentiful, ample amounts, and 「じゃぶじゃぶ」 for pouring liquid generously and vigorously; the latter is limited to that pouring sense.
