Etymology
Origin of conformation
1505–15; < Latin confōrmātiōn- (stem of confōrmātiō ), equivalent to confōrmāt ( us ) past participle of confōrmāre to shape ( con- con- + fōrm ( a ) form + -āt ( us ) -ate 1 ) + -iōn- -ion
Explanation
Conformation can mean following the rules, or fitting in. Competitions require conformation from competitors who must follow the rules of the game. You might note water's conformation to the shape of whatever container that holds it. Conformation has its base in the word conform, which means to follow the rules, or behave in such a way that you fit in, in a social or a spatial way (i.e. adjusting to something else's contours). Conformation should not be confused with confirmation, which means showing the truth or accuracy of something. The two words do have similar religious meanings though. Conformation refers to complying with the rules of a church, while confirmation means a person's full entry into the Christian belief.
