paleolithic

the term paleolithic is a modern scientific compound, constructed in the 19th century from classical greek roots to classify prehistoric human culture. the first element, 'paleo-', derives from the greek 'palaios', meaning ancient or old, which itself can be traced back to the proto-indo-european root kwel-, relating to far away in time or space. the second element, '-lith', originates from the greek 'lithos' for stone, a word of uncertain pre-greek origin. combined with the adjectival suffix '-ic', from greek '-ikos', the word literally means 'of or pertaining to the ancient stone age'. this nomenclature logically reflects the period's defining characteristic: the use of chipped or flaked stone tools by early human societies.

Structure: paleo (ancient) + lith (stone) + ic (adjective suffix) paleo (from greek 'palaios', meaning old or ancient); lith (from greek 'lithos', meaning stone); ic (from latin '-icus', greek '-ikos', forming adjectives meaning 'of or pertaining to').
