Form and Function both are the determinant of each other. Function always has an effect on expressiveness of building.
Fortress can be recognized by the external for i.e. having fortification of the outer walls of fort. Bridges can be recognized by its form i.e. it is mainly suspended between two fixed poles. Windows can always provide clue to the function.
Example: In case of domestic building size and function of rooms always varies. Sizes of doors and windows always vary in residential building. So, residential buildings can be recognized but the repetitive pattern of doors and windows. Industrial buildings do have a recognizable pattern (larger buildings with small windows can be a heavy industry). Commercial buildings can be recognized by the windows- larger windows with transparent look and have repetitive module.

There are seating and lighting shafts and the over sailing ceiling of the arena. All these forms provide the arena a giant abstraction and are the outcome of practical requirement.
