This was tractus (source also of English tract, tractor, treat, etc), the past participle of Latin trahere ‘pull’. This passed into Old French as trait ‘pulling, draught’, hence ‘harness-strap’, from which English gets trait [16]. Its plural trais was borrowed by English as trace ‘harness-strap’ [14]. Tractus also formed the basis of a Vulgar Latin verb *tractiāre ‘drag’, which evolved into Old French tracier ‘make one’s way’, source of the English verb trace [14].A noun trace was also derived from tracier, and this too was acquired by English as trace [13]. At first it denoted a ‘path’ or ‘track’; the modern sense ‘visible sign’ did not develop until the 17th century.=> attract, contract, tract, tractor, trait, treattrace (v.)late 14c., "follow (a course); draw a line, make an outline of something," also figurative; "ponder, investigate," from Old French tracier "look for, follow, pursue" (12c., Modern French tracer), from Vulgar Latin *tractiare "delineate, score, trace" (source also of Spanish trazar "to trace, devise, plan out," Italian tracciare "to follow by foot"), a frequentative form from Latin tractus "track, course," literally "a drawing out," from past participle stem of trahere "to pull, draw" (see tract (n.1)).
