Not able to freeze or not causing freezing to happen.
The nonfreezing liquid is safe to use in cold temperatures.
Nonfreezing → It is formed from "non-" (meaning not) and "freezing" (from the verb "freeze", which comes from Old English "freosan", meaning to become solid or hard due to cold). The word "nonfreezing" means not becoming solid or hard due to cold.
Think of 'not' ('non-') and 'becoming solid due to cold' ('freezing') — that's why nonfreezing means something that does not freeze.
