Types of cantrip probably. Not all of them because in this world there are ideally countless varieties but everyone would probably know a few here and there. Like asking someone for a light and they flick their pointer finger out with a small flame at its tip. Maybe Doug, the weird IT guy at your work knows more than most and he's a clean freak with spotless clothing nearly all the time.
Of course there might be cabals of the magical elite who turn their nose up at everyone else because their families had the money for higher magical education, or idiot savants and the professorial, but I'm more interested in how a setting with magic so commonplace would square with technology and the average disposition of human nature and the breadth of failure and compromise many people experience with their own limitations. Like magic in the military is obvious but are there trade schools for magic? Or how would the public school variant for sorcery studies look? If everyone knows a little magic as a matter of course, what about the magical working class and the community collage of magical aptitude?
