Embossment is formed from "emboss" (from Old French *embosser*, meaning to raise or protrude) and the suffix "-ment" (meaning the action or result of). The word refers to the action or result of creating a raised design on a surface.
Think of the action of raising a design ('emboss') and the result of that action ('-ment') — that's what embossment means.
