figure: [13] Figure comes via Old French from Latin figūra ‘form, shape, figure’, a derivative of the same base (*fig-) as produced fingere ‘make, shape’ (whence English effigy, faint, feign, and fiction). Many of the technical Latin uses of the word, including ‘geometric figure’, are direct translations of Greek skhéma, which also meant literally ‘form, shape’, but the sense ‘numerical symbol’ is a later development. Also from the base *fig- was derived Latin figmentum ‘something created or invented’, from which English gets figment [15].

c. 1200, "numeral;" mid-13c., "visible appearance of a person;" late 14c., "visible and tangible form of anything," from Old French figure "shape, body; form of a word; figure of speech; symbol, allegory" (10c), from Latin figura "a shape, form, figure; quality, kind, style; figure of speech," in Late Latin "a sketch, drawing," from PIE *dheigh- "to form, build" (see dough).

Philosophical and scientific senses are from use of Latin figura to translate Greek skhema. Meaning "lines forming a shape" is from mid-14c. From mid-14c. as "human body as represented by art;" late 15c. as "a body, the human form as a whole." The rhetorical use of figure, "peculiar use of words giving meaning different from usual," dates to late 14c.; hence figure of speech (by 1704). Figure-skating is from 1835. Figure eight as a shape was originally figure of eight (c. 1600). From late 14c. as "a cut or diagram inserted in text."
