The correct spelling is-

✅ কেন সঠিক: The correct spelling is ‘humorous’. Even in British English, where the noun is ‘humour’, the adjective drops the ‘u’: humorous.

❌ অন্য অপশন: ‘Humourous’ is a common mistake; ‘humourious’ and ‘humorious’ add a wrong ‘i’.

💡 মনে রাখুন: humour (BrE) / humor (AmE) → humorous in both. Similarly: vigour → vigorous, glamour → glamorous.
