フリーズ

• Reading: フリーズ
• Romaji: furiizu
• Pronunciation: /ɸu.ɾiː.zu/

Meaning

Freeze — when a device, app, or screen becomes completely unresponsive and stops reacting to input.

Borrowed from English 'freeze,' this term describes the frustrating moment when a device or application stops responding entirely. Unlike 落ちる (crash), where the app shuts down, フリーズ means the screen is stuck — you can see it but cannot interact with it. The term is universally understood and used in both casual and professional tech contexts.

Examples

1. パソコンがフリーズして何も動かない、助けて。 My computer froze and nothing will move — help me.
2. アプリがフリーズしたから一回閉じて開き直した。 The app froze so I closed it and reopened it.
3. 動画編集中にフリーズするの本当に勘弁してほしい。 I really can't deal with it freezing while I'm editing a video.

Do Say

Don't Say

• フリーズと落ちるを混同しない — フリーズは固まる、落ちるは終了する (Don't confuse freeze with crash — freeze means stuck, crash means shut down)

Common Mistakes
