Nonedible → It is formed from "non-" (meaning not) and "edible" (from Latin "edibilis", meaning able to be eaten). The word "nonedible" means not able to be eaten or unsuitable for consumption.
Think of 'non-' meaning 'not' and 'edible' meaning 'able to be eaten' — so nonedible refers to something that is not suitable for eating.
