The literary Polish language was finally established in the 16th century, and since then great number of literature sources exist. And though Polish suffered great Latin , French, German influence through its history, it is still pure Slavic. Nowadays Polish also includes the Kashubian dialect, which used to be a single language but is now practically assimilated. Contemporary Polish has 7 vowel sounds and 35 consonant sounds, depicted by a modified Latin alphabet. The so-called Slavic perfect is the only past tense form used in common speech.
Word order remains highly flexible.
