Discussion

c.1340, from O.Fr. discussion, from L.L. discussionem "examination, discussion," in classical L., "a shaking," from discussus, pp. of discutere "strike asunder, break up," from dis- "apart" + quatere "to shake." Originally "examination, investigation, judicial trial;" meaning of "talk over, debate" first recorded 1448. Sense evolution in L. appears to have been from "smash apart" to "scatter, disperse," then in post-classical times (via the mental process involved) to "investigate, examine," then to "debate."
