Is There a Grammar of a Language That's Not Well Studied?

There's always a chance that something is missing just because we don't have documentation for it. That's something that we should always warn about when people are looking at like the syllogrammers or any grammar of a language not very well studied. But I mean, if you're looking at a language as a model and you know that it's not been studied that much, maybe there's this one reference grammar you found. You can sort of choose whether or not you want to fill in the gaps just as part of your creative decisions when you're transferring these systems into your own con line. So yeah. Shall we move on to verbs? Yes. Let's see. Wacky verbs.
