"Since I am in any case tied up with the eastern mummery for some weeks, I have made use of the opportunity to learn Persian. I am put off Arabic, partly by my inborn hatred of Semitic languages, partly by the impossibility of getting anywhere, without considerable expenditure of time, in so extensive a language — one which has 4,000 roots and goes back over 2,000-3,000 years. By comparison, Persian is absolute child’s play. Were it not for that damned Arabic alphabet in which every half dozen letters looks like every other half dozen and the vowels are not written, I would undertake to learn the entire grammar within 48 hours. This for the better encouragement of Pieper should he feel the urge to imitate me in this poor joke. I have set myself a maximum of three weeks for Persian, so if he stakes two months on it he'll best me anyway. What a pity Weitling can’t speak Persian; he would then have his langue universelle toute trouvie [universal language ready-made] since it is, to my knowledge, the only language where ‘me’ and ‘to me’ are never at odds, the dative and accusative always being the same." Engels to Marx, Manchester, 06 June 1853
