Here are some possibilities:
* "Dumna" might be a misspelling of "Dumni," which means "tail" in Punjabi. This could be used in a playful or informal context.
* It could be a slang term specific to a particular region or community. Without more context, it's difficult to pinpoint the exact meaning.
To get a more accurate translation, please provide more context:
* What was the word used in? (e.g., a conversation, a song, a story)
* What was the general topic or subject matter?
* Did the word have any specific connotations?
