How to say "colossal" in Japanese

Choosing the right word
  • 膨大ぼうだいJLPT N2approx.Common

    Intel gets a huge royalty from the invention.
  • 莫大ばくだいJLPT N3approx.Common
    na-adjectiveCovers 'colossal' as an enormous sum or amount, above all with money: costs, losses, profits, debts. It points to the magnitude of the figure itself rather than to physical size or volume.

    John inherited a large fortune.
  • 絶大ぜつだいCommon
    na-adjective, nounCovers 'colossal' only in the sense of overwhelming degree: influence, popularity, support, or trust. For physical size or sums of money it is not the word; it expresses overwhelming intensity, not bulk.

    Genius has been defined as a supreme capacity for taking trouble.

Choose by the kind of largeness: 膨大 stresses sheer quantity or volume, 莫大 enormous sums, especially of money, and 絶大 overwhelming degree of abstract things like influence or popularity.
