Formation

Notes

The ます-stem noun 〜通どおし is often the commoner surface: 立たち通どおし
and 働はたらき通どおし name the unbroken stretch itself rather than the
act, and take だ（一日中いちにちじゅう立たち通どおしだった）.

Related patterns

Similar

  • 〜切る

    切る measures the action against its OBJECT and claims nothing is left over (読み切る — every page); 通す measures it against the STRETCH it ran and claims no break in it, which is why 八時間はちじかん歩あるき通とおした is ordinary while 歩あるき切きった needs a stated distance for there to be anything to exhaust.

  • 続ける

    続ける states only that the activity did not stop, and any duration will do; 通す additionally frames a bounded span as covered end to end, so the sentence normally names it (最後さいごまで, 朝あさまで) where 走はしり続つづける names nothing.

  • 抜く

    Both carry an activity to its end, but 抜く asserts hardship overcome where 通す asserts only unbrokenness — やり通とおす is seeing it through, やり抜ぬく is forcing it through against resistance, and 最後さいごまで読よみ通とおした names no adversity at all.

  • っぱなし

    The same unbroken stretch, judged in opposite directions — 働はたらき通とおした credits the subject with deliberate persistence, 働はたらきっぱなしだった complains that no break was ever given.
