Пра падежи и глаголов суть

Я-то полагал, что английскому языку череда завоевателей развиться не дала, и вот он такой шаблонный и остался, а оказывается, нормальный язык был Old English (5-11 века), просто жадность сгубила :)

  Declension occurs in many of the world's languages, and features very prominently in many European languages, including Old English, but is much less prominent in Modern English. In contrast to Old English, at least 80 percent of the vocabulary of Modern English has been borrowed from foreign, mostly non-Germanic languages (especially Latin), whose systems of declension conflicted with those of Old English. The resulting compromises effectively eliminated most forms of inflection in late Middle and Modern English...
