service-sector

The term "service-sector" is a modern compound noun formed in the 20th century to describe a specific economic category. Its first element, "service", originates from the Latin concept of 'servitium', denoting the condition of a servant or slave, which semantically broadened to encompass any non-material work performed for others. The second element, "sector", derives from the Latin 'secare', meaning to cut, and evolved to signify a distinct segment carved out from a larger whole, such as an economy. The compound logically combines these ideas to define the segment of economic activity dedicated to providing intangible assistance, expertise, or labour, as opposed to producing physical commodities, reflecting the post-industrial shift in economic analysis.
