Sense: noun/1

Entity is the most formal and precise of these words. It emphasises that something has its own independent existence and can be treated as a whole. Thing is the most general and informal — any object, idea, or action can be called a thing, but it does not carry the sense of being a complete, separate unit. Unit highlights the idea of being one part of a larger system (a family unit within a community). Body is used for groups of people acting collectively, especially in official or institutional contexts (the student body, a regulatory body). Organization is narrower and refers specifically to a structured group of people with a stated purpose, such as a business or charity. Use entity when you want to stress that something exists independently and is recognised as a whole, especially in formal, legal, or academic writing.

Etymology

LatinMedieval LatinEnglish

Entity comes from the Latin word 'entitas', which means 'being' or 'existence'. This in turn came from 'ens' (a thing that exists), formed from 'esse' (to be). The word entered English in the late 1500s through medieval Latin, at first used mainly in philosophy and theology to talk about the nature of existence, and later spread to law, business, and everyday use.
