Word History

Etymology

Verb

Middle English bannen "to summon (troops) by proclamation, assemble (an armed force), gather (arms), curse, anathematize, prohibit, outlaw," going back to Old English bannan (class VII strong verb) "to summon by proclamation, call to arms," going back to Germanic *bannan- "to speak formally, call on, order" (whence also Old Frisian bonna, banna "to call upon, command, place under a ban," Old Saxon & Old High German bannan "to summon, order," Old Norse banna "to prohibit, curse"), going back to Indo-European *b^ho-n-h₂-e-, presumed o-grade intensive derivative (with gemination from a present formation with *-nu̯-e-?) from a verbal base *b^heh₂- "speak, say," whence also Latin for, fārī "to speak, say," Greek phēmí, phánai, Armenian bay "(s/he) says, speaks," and with extensions Eastern Church Slavic baju, bajati "to tell (stories), cast a spell, cure," Bosnian-Croatian-Serbian bȁjati "to tell tales, practice sorcery," Sanskrit bhánati "(s/he) speaks, says, (it) sounds"

Note: The senses "curse, anathematize, prohibit," etc., in Middle English are not attested in Old English and are generally thought to reflect influence of the cognate Old Norse verb. The English verb has also been influenced in sense by Medieval Latin bannīre and Old French banir (see banish). — The reconstruction of the source of Germanic *bannan- in Indo-European terms is from G. Kroonen, Etymological Dictionary of Proto-Germanic (Brill, 2013), though any number of alternative reconstructions are possible that result in the new verbal base *bann-. Indo-European *b^heh₂- "speak, say" is phonetically identical with and probably a semantic offshoot of the base *b^heh₂- "shine, give light, appear" (see fantasy entry 1); the presumed sense in shift would be "shine, give light" > "make bright, illuminate" > "make clear, clarify" > "speak, say."

Noun (1)

Middle English ban, bane, banne "proclamation by an authority, summons, one of the marriage banns, troop of warriors summoned by their overlord," in part noun derivative of bannen "to summon (troops) by proclamation," in part borrowed from Anglo-French ban, baan "proclamation, edict, jurisdiction, one of the marriage banns" (also continental Old French, "summons to arms by a lord, proclamation commanding or prohibiting an action"), going back to Old Low Franconian *banna-, going back to Germanic (whence also Old Frisian bon, ban, bān "order commanding or prohibiting under pain of a fine, authority, summoning of the army, banishment," Old Saxon bann "command, summons, fine, excommunication," Old High German ban "command by an authority, order, legal extension or withdrawal of protection"), noun derivative of *bannan- "to speak formally, call on, order" — more at ban entry 1

Note: The Middle English noun may also continue Old English gebann, gebenn "edict, proclamation, command," a derivative of gebannan, similar in meaning to unprefixed bannan. The negative senses "prohibition, condemnation," etc., though present to a limited degree already in early Medieval Latin, do not appear in English (or French) until the sixteenth century, and are in part derived from the verb ban entry 1. The Germanic etymon appears in Latin as bannus (or bannum), from the sixth century in Gregory of Tours' Historia Francorum, and the seventh century in the Lex Ripuaria, the laws of the Ripuarian Franks; the Latin word went on to develop a broad range of meanings (compare the entries in J. F. Niermeyer, Mediae Latinitatis lexicon minus and Dictionary of Medieval Latin from British Sources).
