As a concept in linguistics and pedagogy in general, it's important to remind people that just because you don't have or can't use a word for what something is, that doesn't mean you should call it something it isn't. It may be appropriate in a given context to simplify a concept as such when that's the only part of it we're working with, but in terms of understanding the thing itself, just taking that simplification as if it fully is the thing is so not helpful.
