Architecture is about WHY

Yet another definition of architecture which may be more understandable by some audiences.

MASTER definition

architecture, noun
totality of fundamental concepts or properties of a system in its environment embodied in its discrete parts and relationships, and in the principles of its design and evolution

Another definition

architecture of a system-of-interest, noun
description why this system-of-interest is designed as shown in its blueprint

Such a description must be
- explicit
- computer-executable (i.e. formalised)
- multi-viewpoints
- understandable by all the stakeholders of the system-of-interest

A blueprint of a system-of-interest is only one of the architecture description viewpoints.
