I filled out my latest version of notes on conlanging some more today. I noted some basic aspects of mood that I want to somehow implement, though I'm not sure how I want to do it, exactly. My original idea was to have most aspect-mood information conveyed using auxiliary verbs, more or less, though I'm not sure if using an auxiliary to communicate the imperative mood is a thing much.
One thing that just occurred to me as a possibility is to form contractions with pronouns and auxiliaries.
Anyway, I thought I was going to finish this post twenty minutes ago and I spaced out. I'm going to need to get better about getting sleep if I want to make more substantial posts...
