umpire: [15] An umpire is etymologically someone who is ‘not the equal’ of others, and is therefore neutral between them. The word’s ultimate source is Old French nomper, a compound noun formed from the prefix non- ‘not’ and per ‘equal’ (source of English peer). This was borrowed into English in the 14th century as noumpere, but soon misdivision of a noumpere as an oumpere led to umpire (the same process produced adder from an original nadder). => peer
umpire (n.)
mid-14c., noumper, from Old French nonper "odd number, not even," in reference to a third person to arbitrate between two, from non "not" (see non-) + per "equal," from Latin par (see par). Initial -n- lost by mid-15c. due to faulty separation of a noumpere, heard as an oumpere. Originally legal, the gaming sense first recorded 1714 (in wrestling).
umpire (v.)
1610s, from umpire (n.). Related: Umpired; umpiring.
