An earlier sense of effigy is "a likeness of a person shaped out of stone or other materials," so it's not surprising to learn that effigy derives, by way of Middle French, from the Latin effigies, which, in turn, comes from the verb effingere ("to form"), a combination of the prefix ­ex- and fingere, which means "to shape." Fingere is the common ancestor of a number of other English nouns that name things you can shape. A fiction is a story you shape with your imagination. Figments are shaped by the imagination, too; they're something you imagine or make up. A figure can be a numeral, a shape, or a picture that you shape as you draw or write.
