Word origin
[1885–90; ammoni(a) + -fication]This word is first recorded in the period 1885–90. Other words that entered Englishat around the same time include: lineup, reactor, retread, roller coaster, scrum-fication is a combining form of nouns of action or state corresponding to verbs ending in-fy. Other words that use the affix -fication include: deification, pacification
