I'm not sure how to feel about this. On one side all 'Legacy tools' like translator or dictionary warn me in very dangerous looking yellow font, that they are not reliable and I shouldn't use them. But it's hard with dictionary of ~600 canon words to have even basic-level conversation, so fan made words come in handy.

Still I'm worried how much Average Dovahzul Enjoyer would understand from my tinvaak. Everyone on this site seem to use strictly canon. So my questions are: how common is to learn and use non-canon words in this community? Am I allowed to use non-canon at forums?

I'm about to DM a new Dungeons & Dragons campaign in a homebrewed world, and I'm planning to use Dovahzul for the in-universe equivalent of Draconic (much larger lexicon than many other dragon conlangs). I may be forced to use non-canon sources whether I want to or not.
