Verb perfect, _sdvigat'_, to move completely. The reader may judge for himself, of what precision, compactness, and energy, a language is capable, which has so little need of circumlocution. It must be mentioned, however, that not all these verbs are complete; as indeed it is obvious from their very nature, that in many of them, various tenses must be wanting. It is probably for this reason, that some of the most distinguished grammarians do not acknowledge this division of the verb itself; but put all its variations under the conjugation of a single verb, as different tenses,--a proceeding which contributes much to make the Slavic grammar a horror to all foreigners. If this short and meagre sketch is hardly sufficient to give the reader an idea of the richness, precision, and general perfectibility of the Slavic languages, it will be still more difficult to reconcile his mind to their _sound_; against which the most decided prejudices exist among all foreigners. The old Slavic alphabet has forty-six letters; and from this variety it can justly be concluded, that the language had originally at least nearly as many different sounds, although a great part of them are no longer to be found in the modern Slavic languages. It is true, that all the dialects are comparatively poor in vowels, and, like the oriental languages; utterly deficient in diphthongs.[17] They have neither the _oe_ nor _ue_, which the Germans consider as the best sounds of their idiom: nor the Greek,[Greek: ei], [Greek: ui], [Greek: au], [Greek: eu], and the like; still less the variety of pronunciation of one and the same vowel, peculiar to the English. The Poles, Russians, and Bohemians, possess however a twofold _i_, [18] a finer and a coarser one; the latter of which is not to be found in any other European language, and is unpleasant to the ear of foreigners. The Poles, besides this, have _nasal vowels_, as other languages have nasal consonants.[19]
