Befuddled Questioning...

I woke up with the word "modality" dancing, like a wave, or light beam, in my head. My reaction? Hunh? You know, befuddled questioning. I had to look up the meaning this a.m.

"Modality is about a speaker’s or a writer’s attitude towards the world. A speaker or writer can express certainty, possibility, willingness, obligation, necessity and ability by using modal words and expressions. Speakers often have different opinions about the same thing. These speakers are looking at the same thing."

"Here are the main verbs we use to express modal meanings: Core modal verbs: can, could, may, might, will, shall, would, should, must, Semi-modals: dare, need, ought to, used to"

Right. Necessity and ability.  Kind of defines the boundaries our lives & days, and well, modality opens a whole can of worms.
