ban (v.) Look up ban at Dictionary.com
Old English bannan "to summon, command, proclaim," from Proto-Germanic *bannan "proclaim, command, summon, outlaw, forbid" (source also of Old High German bannan "to command or forbid under threat of punishment," German bannen "banish, expel, curse"), originally "to speak publicly," from PIE root *bha- (2) "to speak" (source also of Old Irish bann "law," Armenian ban "word;" see fame (n.)).

Main modern sense of "to prohibit" (late 14c.) is from Old Norse cognate banna "to curse, prohibit," and probably in part from Old French ban, which meant "outlawry, banishment," among other things (see banal) and was a borrowing from Germanic. The sense evolution in Germanic was from "speak" to "proclaim a threat" to (in Norse, German, etc.) "curse."

The Germanic root, borrowed in Latin and French, has been productive: banish, bandit, contraband, etc. Related: Banned; banning. Banned in Boston dates from 1920s, in allusion to the excessive zeal and power of that city's Watch and Ward Society.

band (n.1) Look up band at Dictionary.com
"a flat strip," also "something that binds," a merger of two words, ultimately from the same source. In the sense "that by which someone or something is bound," it is attested from early 12c., from Old Norse band "thin strip that ties or constrains," from Proto-Germanic *bindan, from PIE *bendh- "to bind" (source also of Gothic bandi "that which binds; Sanskrit bandhah "a tying, bandage," source of bandana; Middle Irish bainna "bracelet;" see bend (v.), bind (v.)). Most of the figurative senses of this word have passed into bond (n.), which originally was a phonetic variant of this band.

The meaning "a flat strip" (late 14c.) is from Old French bande "strip, edge, side," via Old North French bende, from Old High German binda, from Proto-Germanic *bindan (see above). In Middle English, this was distinguished by the spelling bande, but since the loss of the final -e the words have fully merged.

Band saw is recorded from 1864.
