beam

{{11}}beam (n.) O.E. beam originally "living tree," but by late 10c. also "rafter, post, ship's timber," from W.Gmc. *baumaz (Cf. O.Fris. bam "tree, gallows, beam," M.Du. boom, O.H.G. boum, Ger. Baum "tree"), perhaps from PIE verb root *bheue- "to grow" (see BE (Cf. be)). Meaning "ray of light" developed in O.E., probably because it was used by Bede to render L. columna lucis, the Biblical "pillar of fire." Nautical sense of "one of the horizontal transverse timbers holding a ship together" is from early 13c., hence "greatest breadth of a ship," and slang broad in the beam "wide-hipped" (of persons). To be on the beam (1941) was originally an aviator's term for "to follow the course indicated by a radio beam."
{{12}}beam (v.) "emit rays of light," early 15c., from BEAM (Cf. beam) (n.) in the "ray of light" sense. Sense of "to smile radiantly" is from 1804; that of "to direct radio transmissions" is from 1927. Related: Beamed; beaming.
