The results of the study show that the English language has moved from being a highly inflective, synthetic language with many endings and cases, few prepositions and no real articles, to developing into a more analytic language with fewer inflectional markers and cases, the system of grammar was so complicated than today, the study offered some recommendation that encourage more studies in the scope of the language change.
