n.

old english beacen “sign, portent, lighthouse,” from west germanic -baukna “beacon, signal” (cf. old frisian baken, old saxon bokan, old high german bouhhan); not found outside germanic. perhaps borrowed from latin bucina “a crooked horn or trumpet, signal horn.” but more likely from pie -bhew-, a variant of the base -bha- “to gleam, shine” (see phantasm). figurative use from c.1600.

a pole (heb. to’ren) used as a standard or ensign set on the tops of mountains as a call to the people to -ssemble themselves for some great national purpose (isa. 30:17). in isa. 33:23 and ezek. 27:5, the same word is rendered “mast.” (see banner.)
