Origin: 1275–1325; ME ordinaunce (< OF ordenance) < ML ordinantia, deriv. of L ordinant- (s. of ordināns), prp. of ordināre to arrange. See ordination, -ance
A statute or regulation, especially one enacted by a city government.
[Middle English ordinaunce, from Old French ordenance, from Medieval Latin ōrdinantia, from Latin ōrdināns, ōrdinant-, present participle of ōrdināre, to ordain, from ōrdō, ōrdin-, order; see ar- in Indo-European roots.]
1303, "an authoritative direction, decree, or command" (narrower or more transitory than a law), from O.Fr. ordenance, from M.L. ordinantia, from L. ordinantem (nom. ordinans), prp. of ordinare "put in order" (see ordain). By c.1330 senses had emerged of "arrangement in ranks or rows" (especially in order of battle), also "warlike provisions, equipment" (a sense now in ordnance, q.v.).
