Nonteaching → It is formed from "non-" (meaning not) and "teaching" (from Old English "tǣcan", meaning to show or instruct). The word "nonteaching" refers to something that is not related to or does not involve teaching.
Think of 'non-' meaning 'not' and 'teaching' as showing or instructing — so nonteaching means not involved in teaching.
