With Number 2, I remember being confused when we were asked about the word "break", in Year Three. The teacher asked us to give a different meaning for it from to "break something." At the time, I thought, "Well, there's brake, for what makes a vehicle stop." I also thought, "Okay, break can be a noun as well as a verb." The teacher gave the example of when you have a break, like morning tea, and I thought, "That's the same meaning, in that, say for a commercial break, it's a break in the program." The meaning I hadn't heard of, until many years later, was when they say, "That singer got their big break," what they mean there is, "That singer became famous."
