nitrification in American English
(ˌnaitrəfɪˈkeiʃən)
noun
the act of nitrifying
Word origin
[1820–30; nitr- + -i- + -fication]This word is first recorded in the period 1820–30. Other words that entered Englishat around the same time include: acetate, insider, karma, myth, tetrapod-i- is the typical ending of the first element of compounds of Latin words, as -o- is of Greek words, but often used in English with a first element of any origin,if the second element is of Latin origin. Other words that use the affix -i- include: Frenchify, cuneiform; -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
