The wedge is one of the simplest machines, converting forward force into pressure directed sideways. Made from wood, stone, or metal, it is used in splitting logs, quarrying, construction, and securing handles or doors. In poetry it often symbolises division, leverage, and the small beginning of a large rupture. Once inserted into a crack, it can widen separation with each blow, making it apt for jealousy, conflict, or doubt; alternatively, it may hold open a passage or secure a structure.

The wedge is one of the simplest machines, transforming force applied in one direction into pressure directed sideways. It may split logs, lift stones, tighten joints, secure handles, or hold doors open. In poetry a small wedge can represent doubt, jealousy, or conflict widening an existing crack. More positively, it may preserve an opening or multiply limited strength. Related terms include maul, froe, lever, splitting, crack, pressure, timber, stone, separation, leverage, division, support, access, and the large consequences produced by a small intervention.
