すまん

• Reading: すまん
• Romaji: suman
• Pronunciation: /sɯ.maɴ/

Meaning

Sorry — a casual, masculine apology derived from すみません.

すまん is a rough, casual contraction of すみません that carries a distinctly masculine tone. It is commonly heard among male friends, in manga/anime dialogue, and in casual settings. While it expresses genuine apology, its gruff delivery signals comfortable familiarity rather than deep remorse. The even shorter すまね is sometimes used for extra casualness.

Examples

1. すまん、遅れた！道混んでた。 Sorry, I'm late! Traffic was bad.
2. すまん、それ俺のミスだわ。 Sorry, that was my mistake.
3. すまんけど、ちょっと手伝ってくれない？ Sorry, but could you give me a hand?
