410 The Loom of Language for construction of compound tenses, we can express with 20 words everything for which Sanskrit burdens the memory with nearly forty times as many different vocables MODERN LANGUAGES OF THE EAST Dunng the past two thousand years theie has been a universal drift among Aryan languages towards reduction and regularization of flexion This tendency towards economy of effort is as striking on the Eastern front as on the Western., and in no language more than in modern Persian and Hindustani After the Islamic conquest, Persian suffered a heavy infiltration of Arabic words Consequently its present vocabu- lary is as Semitic as it is indigenous Even Semitic grammatical forms crept in, but these affect only Arabic words There can be little doubt that the decay of Persian flexions was accelerated by the Moslem conquest In fact, Persian and Anglo- American provide an impressive example of parallel evolution from similar beginnings.
