Definitions

1. A horizontal structural member across a doorway or window, often supporting a partition or containing glass

Etymology: "Transoms" is the plural of "transom," a horizontal beam or bar. The singular has a double life: the crossbar above a doorway or window, often a fanlight or decorative panel, and the horizontal crosspiece across the stern of a boat. Both senses share the same basic idea of a beam laid across an opening or frame. The word reached English in Middle English as "traunsom," and it likely alters Latin "transtrum," meaning "crossbeam." The Latin term itself came from "trans," meaning "across," so the word's core meaning is simply something lying across. Its shape shifted over the centuries, with the vowel and spelling changing until it settled into the modern form.

Synonyms: crossbar, beam, lintel, framework, support
