what being plain means
Plain things are simple, unadorned, and even a little boring. Being a plain talker means you don't use pretentious, fancy words. But having a plain face means you're not much to look at. Plain comes from the Latin word planum, meaning level ground.. That's one meaning of the word, as in a flat prairie or low lying coastal flood plain. If something is in plain view, it's out in the open with no obstructions.
