A structural base or pedestal, most often referring to the foundational socket or block upon which uprights (such as pillars, boards, doorposts) are set; in tabernacle contexts, the shaped slabs (usually silver or bronze) that provided stability for vertical elements. The word denotes the literal, tangible base supporting a structure or component. Secondary usage may refer to the concept of a supporting foundation more generally, but always with physical or architectural connotation.
