dictionary – Where are dictionaries stored in MacOS?

I’m studying the Dutch language, and the built-in dictionary has plenty of example sentences that are superior to the ones in the materials I’ve been working with from Loecsen.  I’d like to put many of them (a few at a time) into Anki for memory drill.

But Apple has disabled copy on the pop-up. Perhaps that’s a copyright issue, in which case my question is irrelevant. But if not, I’d like some way to get to them other than screen shot, OCR, and cleanup.

The same dictionary is also on my iPad, so a way to access that would be useful as well.

I found many possible packages in /System/Library/AssetsV2/com_apple_MobileAsset_DictionaryServices_dictionaryOSX but don’t see any way to parse them.
