Foment → It is formed from "fomentum" (meaning a poultice or soothing application) and the suffix "-ent" (indicating an agent or something that performs an action). The word "foment" originally referred to the act of applying a soothing substance, and it has evolved to mean instigating or promoting something, often in a more abstract sense.
Think of applying a soothing substance ('fomentum') to help something grow or develop — that's why foment means to promote or instigate.
