Word Origin & History

beam 
O.E. beam originally "living tree," but by 1000 also "post, ship's timber," from W.Gmc. *baumoz (cf. O.Fris. bam, Du. boom, Ger. Baum "tree"), perhaps from PIE verb root *bu- "to grow." Meaning of "ray of light" developed in O.E., probably because it was used by Bede to render L. columna lucis, Biblical "pillar of fire." Nautical sense of "one of the horizontal transverse timbers holding a ship together" is from 1627, hence "greatest breadth of a ship," and slang broad in the beam "wide-hipped" (of persons). The verb meaning "emit rays of light" is from c.1440; sense of "to smile radiantly" is from 1893; that of "to direct radio transmissions" is from 1927. To be on the beam (1941) was originally an aviator's term for "to follow the course indicated by a radio beam." Lewis Carroll may have thought he was inventing beamish in "Jabberwocky," but it is attested from 1530.
