Notes on Meaning

The two definitions are closely related but specify slightly different scopes: 1. The first definition is more precise, specifying porticoes with free columns at both ends. 2. The second definition is slightly more general, allowing for columns at both ends OR both sides. In practice, "amphistylar" most commonly refers to a building with columned porticoes at the front and rear (both ends).
