Root Explanation

Combustibility is formed from "com-" (meaning together) and "bust" (from Latin "urere", meaning to burn) and the suffix "-ibility" (meaning the quality of being). The word refers to the quality of being able to burn together or easily.

Memory Tip

Think of something that has the quality of being able to 'burn' ('bust') when things come 'together' ('com-'). This helps you remember that combustibility refers to how easily something can catch fire.
