As regards grammar, there are a few grammatical differences between Early modern English and Late modern English, such as differences in adjective gradation, pronouns and determiners, verbs conjugation, and sentence structure, among others. These changes contributed significantly to the incongruity between spelling and pronunciation. As for pronunciation, various sound changes were having a far-reaching effect on it, chief among which was the so-called ‘Great Vowel Shift’. There are noticeable differences in the look of printed English before the mid-seventeenth century, but after that date it is largely the same as modern English. Between 1475 and about 1630 English spelling gradually became regularized. In the late-fifteenth century printers began printing books written in the form of London English which had already become a kind of standard in manuscript documents.
