[…] we have first monemes that carry within themselves the indication of their own function and which we shall designate as autonomous monemes: French 'vite', 'hier', 'demain', 'dimanche' in 'il viendra dimanche', are autonomous monemes; in English there seem to be few clearly autonomous monemes of that type, but autonomous compound such as last night, next week are at least as frequent as in French, where we have 'hier soir', 'la semaine prochaine'. Notice in German, autonomous compound numerals such as 'neunzehnhundertneununddreissig' with meaning of ‘in 1939’.
