ちわ

• Reading: ちわ
• Romaji: chiwa
• Pronunciation: /tɕi.wa/

Meaning

Yo / Hey — a very casual, truncated greeting from こんにちは.

ちわ chops こんにちは down to just its final two syllables, creating an ultra-casual greeting. It is used when bumping into acquaintances, arriving at a casual gathering, or as a quick hello. The brevity signals that the speaker is relaxed and familiar with the listener. Often heard in shops from regular customers and among workmates.

Examples

1. ちわ〜、今日も暑いね。 Hey~ it's hot again today, huh.
2. ちわ！もう始まってる？ Hey! Has it already started?
3. ちわっす、お世話になってます。 Hey there, thanks for everything.
