Is there a word for that?

Experts have a word for it. If it’s important, conceptual or frequently discussed, there’s probably a domain-based word that experts understand. The precision of a special vocabulary allows them to do better work.

But…

Just because someone knows the word for it doesn’t mean that they understand, or that they’re a useful expert.

And…

If someone doesn’t know the word for it, it might be worth investigating what else they don’t know.

Domain knowledge and experience are powerful tools.
