1. Bean, legume or pulse?
All three words mean the same thing but in different ways. “Bean” can refer to non-leguminous plants, though, and often doesn’t refer to leguminous ones; for instance, how often do you count peanuts as beans? Yet the peanut is a legume because it is from the old family of plants, Leguminosae (which has been renamed Fabacae, just to make it so much clearer). “Pulse”, on the other hand, tends to refer only to those that are grown to be dried for consumption.
