The quality or state of being eminent; a high-ranking person or an elevated place.
From Latin eminentia through Old French, combining the root eminere (to stand out) with the suffix -cy, which creates abstract nouns expressing a state or condition.
This is the forgotten cousin of 'eminence'—both words mean the same thing, but eminence won the popularity contest and stayed in modern English, while eminency survives mainly in older texts and special contexts like titles.
