In the first place, as regards the alphabet and the pronunciation, our fundamental principle leads to the choice of the Latin alphabet, with the exclusion of all accented or otherwise specially modified letters; neither _ä_, _ö_, _á_, _à_, _â_, _ç_, nor the circumflexed _ĉ_, _ĝ_, _ĥ_, _ĵ_, _ŝ_, especially invented by Dr. Zamenhof for Esperanto, can be tolerated, for they hinder, and sometimes even render impossible, writing, printing, and telegraphing. I have shown in the Introduction to the international dictionaries of De Beaufront and Couturat how our fundamental principle leads to the following alphabet and the following sound values: _a_ (as in _father_), _b_, _c_ (like _ts_), _d_, _e_ (like _e_ in _net_ or like _a_ in _fate_), _f_, _g_ (always hard, as in _go_), _h_, _i_ (like _ee_ in _sweet_), _j_ (either like E.[3] or like F.,[3] as in _journal_), _k_, _l_, _m_, _n_, _o_ (as in _go_ or as in _not_), _p_, _q_ (_qu_, as in G. or as in E.), _r_, _s_ (always unvoiced), _t_, _u_ (always like _oo_, as in _too_), _v_, _x_ (as in G. or as in E. F. in the words _exist_, _exister_), _y_ (as in E. F., and therefore like G. _j_), _z_ (as in E. F., and therefore like the voiced North German _s_ in _rose_), further the two double letters _ch_ (as in E., for example _church_) and _sh_ (as in E., G. _sch_). The strict phonetic canon "One symbol, one sound," is therefore followed in so far as the same sound is never arbitrarily written one way in one word and another way in another word, and the same letter is never pronounced differently in some words compared with the majority. The small exception that _sh_ and _ch_ are not equivalent to _s_ + _h_ and _c_ + _h_ respectively cannot cause the least difficulty to anyone, and the use of _qu_ and _x_ enables us to retain the international spelling of many words, and, moreover, permits two different pronunciations which cause no difficulty of comprehension and simplify the pronunciation for several nations. Otherwise we should be faced with the difficult problem of choosing between _kwala_ and _kvala_, _eksistar_ and _egzistar_. It must not be forgotten, too, that for our purposes the purely theoretical canon "One symbol, one sound," must be subordinated to the fundamental principle of greatest facility, of which phonetic simplicity is itself only a consequence. Practical considerations must, in fact, overrule theoretical objections whenever a small deviation from the fundamental principle "One symbol, one sound," produces greater facility.
