How to say "tremendous" in Japanese

• ものすごいJLPT N2approx.Common
  i-adjectiveThe everyday all-purpose choice: something so great, fast, or intense that it staggers you. Use it when 'tremendous' just means 'amazingly big or impressive' in casual description.
  彼女かのじょはものすごい食欲しょくよくがある。↗

  She has a gigantic appetite.
• 絶大ぜつだいCommon
  na-adjective, nounCovers 'tremendous' in the sense of immense, colossal magnitude, especially of abstract things such as influence, support, or trust. It describes sheer overwhelming scale rather than speed or surprise.
  天才てんさいとは従来じゅうらい、先天的せんてんてきに絶大ぜつだいな努力どりょくをなし得える能力のうりょくを備そなえた者ものとの定義ていぎが下くだされてきた。↗

  Genius has been defined as a supreme capacity for taking trouble.
• 豪快ごうかいCommon
  na-adjective, nounA marginal match for 'tremendous'; its core sense is hearty, magnificent, glorious behavior or style. Reach for it when 'tremendous' describes grand, sweeping flair, not size or degree.
• 甚だしいはなはだしいJLPT N2approx.Common
  i-adjectiveFits 'tremendous' only where it means extreme or excessive in degree, often with a negative coloring, as in a terrible difference or intense hardship. Not the word for neutral 'very large'.
  あんなことを彼女かのじょに言ゆうなんて非常識ひじょうしきも甚はなはだしい。↗

  It's quite absurd of you to tell her that sort of thing.
• 恐ろしいおそろしいJLPT N3approx.Common
  i-adjectiveUse when 'tremendous' carries a startling, fearsome, or amazing force—something whose scale shocks you. It works for tremendous speed, loss, or power that inspires dread or astonishment.

Use 「ものすごい」 for general 'incredibly great' emphasis, 絶大 for immense influence or support, 豪快 for hearty magnificence, 「甚だしい」 for excessive degree, and 「恐ろしい」 when the scale is startling or fearsome.
