Etymology

Origin of constitution

First recorded in 1350–1400; Middle English constitucion “edict, ordinance,” from Anglo-French, from Latin constitūtiōn-, stem of constitūtiō “an appointing, establishing”; constitute, -ion

Explanation

A constitution is a statement of the basic principles and laws of a nation, state, or group, such as the U.S. Constitution. Another very common meaning of constitution is the physical makeup of a person. The noun constitution is from Latin, from constitutus, "set up, established," plus the suffix -ion, meaning "act, state, or condition." So think of a constitution as how a body (yours, the government's) is set up. If you have a strong constitution, it means you don't get sick very often.
