Some languages - human languages, natural or constructed, not programming languages - have ways of expressing the source of a piece of information, such as whether it is a known fact, something you have personally observed, or just an idea you are throwing out there for instance, using grammar or extra signifying words.

I’ve often thought about stealing some of these techniques for note taking as it would be really useful to have extra context without having to write it all out longhand.

Check out lojban attitudinals for one example along these lines if you are interested. There are natural languages that do this as well but I can’t remember any specifics off the top of my head
