落ちる

• 読み: おちる
• ローマ字: ochiru
• 漢字の分解: 落 (fall/drop) + ちる (verb ending) → to fall → to crash (tech meaning)
• 発音: /o.tɕi.ɾu/

意味

To crash — when an app, game, system, or website suddenly stops working or shuts down unexpectedly.

While 落ちる literally means 'to fall,' in tech contexts it is universally used to describe software crashing, servers going down, or systems failing. This usage has been part of Japanese tech vocabulary since the early internet era. It is used across all levels of formality, from casual complaints to semi-formal incident reports.
