 In "Taktika", Arrian (92–175 AD), a Greek historian and philosopher of the Roman period, drew attention to the Romans' indebtedness to their colonial subjects, arguing that "the Romans have many foreign (Iberian, Celtic) terms for formations, for they used Celtic cavalry".In modern times, the French and British resorted to similar linguistic appropriations throughout their conquests.The French language, for example, contains over 200 Arabic and Berber words, most of which were taken up during France's colonization of Algeria.
