Root Explanation

Nonfuel → It is formed from "non-" (meaning not) and "fuel" (from Old French *fueil*, meaning material that produces heat or energy). The word "nonfuel" refers to something that is not a source of fuel or energy.

Memory Tip

Think of 'non-' meaning 'not' and 'fuel' as the material that provides energy. This helps you remember that 'nonfuel' means something that does not provide energy.
