Other forms: architectures
Architecture is the process, or profession, of designing buildings and their environments. Architecture also refers to the product of this design and work.
The root of the word architecture is the Greek arkhitekton ("master builder"), which makes sense because the ancient Greeks were very skilled at architecture — think of all those columns and stadiums and temples. The Parthenon, which was begun in 447 BC, is one of the greatest examples of architecture from Classical Greece.
