Etymology
the word 'sofa' entered english in the early 17th century from the turkish word 'sofa', which denoted a raised, carpeted platform for seating. the turkish term itself was borrowed from the arabic word 'ṣuffa', meaning a long bench or a raised part of the floor covered with carpeting and cushions. this reflects the traditional seating furniture of the middle east and north africa. the english meaning evolved to specify a specific type of upholstered, armrest-equipped furniture for the living room, solidifying its modern sense by the 19th century.
