An architect is a person trained in the planning, design and oversight of the construction of buildings. To practice architecture means to offer or render services in connection with the design and construction of a building, or group of buildings and the space within the site surrounding the buildings, that have as their principal purpose human occupancy or use. Etymologically, architect derives from the Latin architectus, itself derived from the Greek arkhitekton (arkhi-, chief + tekton, builder), i.e. chief builder.
Professionally, an architect's decisions affect public safety, and thus an architect must undergo specialized training consisting of advanced education and a practicum (or internship) for practical experience to earn a license to practice architecture. The practical, technical, and academic requirements for becoming an architect vary by jurisdiction (see below).
The terms architect and architecture are also used in the disciplines of landscape architecture, naval architecture and often information technology (for example a software architect). In most of the world's jurisdictions, the professional and commercial uses of the term "architect", outside of the etymological variants noted, is legally protected.
