Cognate with North Frisian Boom, buum (“tree”), Saterland Frisian Boom (“tree”), West Frisian beam (“tree”), Cimbrian pome, póom, puam (“tree”), Dutch boom (“tree”), German Low German Boom (“tree”), German Baum (“tree”), Luxembourgish Bam (“tree”), Mòcheno pa'm (“tree”), Vilamovian baojm (“tree”), Yiddish בוים (boym, “tree”), Danish, Norwegian Bokmål, Norwegian Nynorsk, and Swedish bom (“beam”), Icelandic baðmur (“tree”), Gothic 𐌱𐌰𐌲𐌼𐍃 (bagms, “tree”), Albanian bimë (“a plant”). Doublet of boom. The original English meaning of beam ("tree") is preserved in some compound words such as quickbeam. The verb is from Middle English bemen, from Old English bēamian (“to shine, to cast forth rays or beams of light”), from the noun.
