A support column is an essential part of many architectural designs. But, sometimes, you might need to find synonyms for this term either to add variety to your writing or to describe a structure that's slightly different from the traditional column. Some common synonyms for support column include pillar, post, beam, pier, stanchion, pylon, and strut. Each of these words carries slightly different connotations. A post, for example, is often smaller and less ornate than a pillar, while a pier typically refers to a column that supports a bridge or other structure over water. Knowing these nuances can help you choose the right synonym for your writing.
