Synfuel → It is formed from "syn-" (from Greek "synthesis", meaning together or with) and "fuel" (from Old French "fouaille", meaning material that produces energy). The word "synfuel" refers to a synthetic fuel created from various sources, combining elements to produce energy.
Think of 'together' ('syn-') and 'energy source' ('fuel') to remember that synfuel is a type of fuel made by combining different materials.
