Beam
Pronunciation
- IPA: /biËm/

Origin
From Middle English beem, from Old English bÄ“am ("tree, cross, gallows, column, pillar, wood, beam, splint, post, stock, rafter, piece of wood"), from Proto-Germanic *baumaz ("tree, beam, balk"), from Proto-Indo-European *bhÅ«- ("to grow, swell").

The verb is from Middle English bemen, from Old English bēamian ("to shine, to cast forth rays or beams of light"), from the noun.
