知らんけど

• Reading: しらんけど
• Romaji: shiran kedo
• Kanji breakdown: 知 (know) + らん (casual negative of ない) + けど (but/though) → don't know, though
• Pronunciation: /ɕi.ɾaɴ.ke.do/

Meaning

I don't actually know though — a disclaimer added after stating an opinion or information to avoid responsibility.

Originally associated with Kansai dialect, 知らんけど has become a national phenomenon used as a catch-all disclaimer. It is appended after making a statement to signal 'don't hold me to this' or 'take this with a grain of salt.' It allows the speaker to share opinions, gossip, or speculation freely while maintaining plausible deniability. Often humorous when used after very confident-sounding statements.

Examples

1. あの二人付き合ってるらしいよ、知らんけど。 Those two are apparently dating — don't quote me though.
2. 明日雨降るって、知らんけど。 I heard it's gonna rain tomorrow — I don't actually know though.
3. あそこのラーメン屋美味しいらしい、知らんけど。 That ramen place is supposed to be good — but I dunno for sure.
