means The particular system of parts or steps that makes something work or happen.

from From Greek 'mechane' (contraption, device, clever means), the same root that gives us 'machine' — itself tangled up with 'mechan,' linked to 'mekhos,' meaning expedient or resourceful trick. The Greeks used it for stage-cranes that lowered gods onto the theater floor (the famous 'deus ex machina'), so the word has always meant a hidden rig making something seem effortless, or divine, from behind the curtain.
