Word origin
[1905–10; prograde (pro-1 + (retro)grade) + -ation]This word is first recorded in the period 1905–10. Other words that entered Englishat around the same time include: aspect ratio, cadre, jazz, overcall, thiamine-ation is used to form nouns from stems ending in -ate (separation) and, on this model, to form nouns from stems of other origin (starvation). Other words that use the affix -ation include: capitalization, complementation, concentration, neutralization, polarization
