An archaic or rare term for the process or result of adjusting something to a proper state or condition.
From 'adjust' + -ation suffix. This Latinate formation appears in older legal and technical texts but is now considered obsolete, replaced by the simpler 'adjustment.'
Medieval scholars loved adding -ation to everything because it sounded more official and Latin-derived—'adjustation' appears in old legal documents, but it's so clunky that English speakers naturally defaulted to 'adjustment,' which flows better.
