It is possible that there is a misunderstanding or a typo in the term. Let's break down the possible meanings of the individual words:
* Dhatu - This refers to a verb root in Sanskrit grammar. It is the base form of a verb from which different verb forms are derived.
* Div - This word doesn't have a direct meaning in Sanskrit. It could be a variation of "deva" (meaning "god") or a misspelling.
Therefore, without more context, it is difficult to determine the intended meaning of "dhatu div".
If you can provide more context or the full sentence where you encountered this term, I might be able to help you understand it better.
