  • beam (n.) Old English beam originally "living tree," but by late 10c. also "rafter, post, ship's timber," from Proto-Germanic *baumaz "tree" (source also of Old Frisian bam "tree, gallows, beam," Middle Dutch boom, Old High German boum, German Baum "tree," and perhaps also (with unexplained sound changes) Old Norse baðmr, Gothic bagms), perhaps from PIE verbal root *bheue- "to be, exist, grow." The shift from *-au- to -ea- is regular in Old English.
