form (n.)

c. 1200, forme, fourme, "semblance, image, likeness," from Old French forme, fourme, "physical form, appearance; pleasing looks; shape, image; way, manner" (12c.), from Latin forma "form, contour, figure, shape; appearance, looks; a fine form, beauty; an outline, a model, pattern, design; sort, kind condition," a word of unknown origin. One theory holds that it is from or cognate with Greek morphe "form, beauty, outward appearance" (see Morpheus) via Etruscan [Klein].

From c. 1300 as "physical shape (of something), contour, outline," of a person, "shape of the body;" also "appearance, likeness;" also "the imprint of an object." From c. 1300 as "correct or appropriate way of doing something; established procedure; traditional usage; formal etiquette." Mid-14c. as "instrument for shaping; a mould;" late 14c. as "way in which something is done," also "pattern of a manufactured object." Used widely from late 14c. in theology and Platonic philosophy with senses "archetype of a thing or class; Platonic essence of a thing; the formative principle." From c. 1300 in law, "a legal agreement; terms of agreement," later "a legal document" (mid-14c.). Meaning "a document with blanks to be filled in" is from 1855. From 1590s as "systematic or orderly arrangement;" from 1610s as "mere ceremony." From 1550s as "a class or rank at school" (from sense "a fixed course of study," late 14c.). Form-fitting (adj.) in reference to clothing is from 1893.

c. 1300, formen, fourmen, "create, give life to, give shape or structure to; make, build, construct, devise," from Old French fourmer "formulate, express; draft, create, shape, mold" (12c.) and directly from Latin formare "to shape, fashion, build," also figurative, from forma "form, contour, figure, shape" (see form (n.)). From late 14c. as "go to make up, be a constituent part of;" intransitive sense "take form, come into form" is from 1722. Related: Formed; forming.
