How to use it

States that ever since A (a major event/change), the state B has continued unbroken to the present. Emphasizes emotion.

  • 「~てからというもの」 = "ever since A, B has continued unbroken until now". A is a milestone of major change.
  • Emphasizes an EMOTIONAL/clearly noticeable ongoing change, stronger than plain 「てから」.
  • B is an ongoing state (usually quite different from before A).

Examples

  • Ever since I quit smoking, my health has been great.

  • Ever since I started living alone, I’ve understood how precious family is.

Keep in mind

  • Verb て-form + からというもの.
  • A is a significant event/change.

Common mistakes

  • Wrong昨日(きのう)食(た)べてからというもの、おいしかった。

    Ever since I moved, my life has changed.

    Correct引(ひ)っ越(こ)してからというもの、生活(せいかつ)が変(か)わった。

    「てからというもの」 is used for a MAJOR-CHANGE milestone + an ongoing state — not for a small, one-time event.

  • Wrong結婚(けっこん)してからというものに、幸(しあわ)せだ。

    Ever since I got married, I've been happy.

    Correct結婚(けっこん)してからというもの、幸(しあわ)せだ。

    Attaches directly — don't add 「に」.

Exam tips

  • 「てからというもの」 = ever since a major event (ongoing, emotional emphasis); different from plain 「てから」.
