What does "Obra Dinn" mean?

[Devilfish]

I'm not being deep, just... the actual name of the ship, does it mean anything? That we know off?

No idea, closest I got was 'Dinn' s Work' in esperanto. Dinn means to serve in Scots Gaelic

I speculate that the name is Indian, which I think is appropriate given that the ship is an East Indiaman.
The name reminds me of that of the titular water-carrier of the Rudyard Kipling poem "Gunga Din". The name "Din", according to users on Quora, is a North Indian name meaning "pitiful", and indeed, according to Ancestry.com, it can be traced back to Sanskrit, meaning "humble". I am also finding that "Din" can have roots in Arabic, meaning "faith", "belief", "religion", etc., which isn't far-fetched either in my opinion, considering India's history with Islam. This doesn't explain the spelling "Dinn", however. My guess is that it's a stylistic "corruption", as Europeans were wont to corrupt words and names foreign to them in past centuries, but even then, I would think the British wouldn't bother with the extra N.
The "Obra" element could be in reference to either of the towns in northern India by that name. After all, surnames can be toponymic, and indeed, the beforementioned "Gunga" allegedly refers to the Ganges river. (I should also mention that, as I understand, the family name comes first in traditional Indian naming conventions.)
This is all rather dubious, of course, being based on a couple assumptions and a few quick Google searches. Also, this would imply that the vessel is named not after an Indian place, but an Indian man - and one of some renown, at that! - which I find most unusual, given how lowly the British must have regarded Indians in general at the time.
But at this point, I think I'm reading into it more deeply than even the developers intended. In conclusion, I don't gather an impression of a deep meaning behind the name "Obra Dinn"; I think the namesake of the ship shall remain as mysterious as the fate that befell her.

Djinn can mean other worldly creatures and obra means work, so could loosely translate as the work of other worldly creatures, which do feature in the game

Actually, based on what you've all said above and a little more research, I would say it probably does have meaning. I'm going to guess it means "humble [wood]work" or "wretched creation/deed"; probably in the sense of "this little game I made" with a pun on "this tiny thing made of sticks and subjected to the almighty forces of nature, time, and God[s]".

This reminds me of the Beatles song "Ob-La-Di, Ob-la-Da".

Fwiw as this old thread is necro'd (presumably from a search)...

Lucas Pope said it doesn't actually mean anything. He was looking at old ship names, didn't like them for sounding mundane, this one came into his head and he liked it because it sounded mysterious. He also said he tried different spellings too before settling on what it eventually became. (eg Obre Dinn, Obora Dinn)
