Modern English
Modern English (sometimes New English or NE as opposed to Middle English and Old English) is the form of the English language spoken since the Great Vowel Shift in England, which began in the late 14th century and was completed in roughly 1550.
English alphabet
The Latin script, introduced by Christian missionaries, began to replace the Anglo-Saxon futhorc from about the 7th century, although the two continued in parallel for some time. As such, the Old English alphabet began to employ parts of the Roman alphabet in its construction. Futhorc influenced the emerging English alphabet by providing it with the letters "thorn" (Þ þ) and "wynn" (Ƿ ƿ). The letter "eth" (Ð ð) was later devised as a modification of "dee" (D d), and finally "yogh" ( ) was created by Norman scribes from the insular "g" in Old English and Irish, and used alongside their Carolingian "g".
