The quality of not being able to catch fire or burn easily.
The nonflammability of the material makes it safe for use in construction.
Nonflammability → It is formed from "non-" (meaning not) and "flammare" (meaning to burn) and "-ability" (meaning the quality of being able to). The word refers to the quality of not being able to burn.
Think of 'not' ('non-') being combined with 'burn' ('flammare') to remember that nonflammability means something that cannot catch fire.
