   • 1869, Alfred Russel Wallace, The Malay Archipelago, volume I, London: Macmillan and Co., page 42:

     Eu vai, serves for "I go," "I went," or, "I will go." Adjectives, too, have been deprived of their feminine and plural terminations, so that the language is reduced to a marvellous simplicity, and, with the admixture of a few Malay words, becomes rather puzzling to one who has heard only the pure Lusitanian.
