In this passage :


おっこっている means "to fall" but as far as I know "to fall" in Japanese is the verb 落ちる (which I see a lot throughout the same book).
What is the original form of おっこっている here, searching in the dictionary I get no results.

1 Answer 1


「おっこちる」is「落ちる」-> link + 「~ている」

    The regular teiru-form of 落っこちる is 落っこている, so there is a sound change (音便) here.

  • @hiroki 「おっこちる」is「落ちる」 -- How does おっこちる differ from 落ちる? Are they interchangeable always? 「~ている」 -- Why is it おっこている, not おっこちている?

    I'm quite curious what the derivation is, but I cannot find any solid information. Any ideas what the おっこ- on the front comes from? Apr 7, 2023 at 23:54
