てかさ

• Reading: てかさ
• Romaji: teka sa
• Pronunciation: /te.ka.sa/

Meaning

A casual discourse marker meaning 'by the way,' 'actually,' or 'anyway' — used to change topics or redirect a conversation.

てかさ is a combination of てか (shortened from というか, 'rather' or 'or should I say') and the sentence-final particle さ (a casual attention-getter). It functions as a smooth topic changer in casual conversation and texting. It can introduce a new subject, redirect the flow of discussion, or bring up something the speaker just thought of. Very natural in LINE conversations and casual group chats.

Examples

1. てかさ、明日の待ち合わせ何時にする？ By the way, what time are we meeting up tomorrow?
2. てかさ、あの映画もう観た？すごいよかったんだけど。 Anyway, have you seen that movie yet? It was so good.
3. 宿題やばいわ。てかさ、昼ごはんなに食べた？ Homework is rough. By the way, what did you eat for lunch?
