One more etymology: LECTURE. This was from reading out loud, back when students did not have copies of the content they could read for themselves. The noun is formed from the Latin verb legere, “to read,” which also gives us the English words legible (readable) and — surprise! — lesson (specifically, a Bible reading or Bible lesson; Latin lectio).

I’m no fan of lecture, and the worst is when the professor just reads aloud from the textbook (I had that happen in — oh irony! — a “History of Education” course I was required to take for my teaching certificate; this was back in the 1990s) or when they read aloud from the Powerpoint slides (now in the digital age).
