Modern English speakers may have to make some effort to understand Early Modern English (c. 1500-c. 1700) as represented by the plays and poetry of William Shakespeare (1564-1616) or the King James translation of the Bible (1611), but it is clearly the same language, whereas understanding more than a few words of Middle English (c. 1150-c. 1500), as in such works as Geoffrey Chaucer’s Canterbury Tales (1387–1400), is likely to be impossible, and Old English (Anglo-Saxon, c. 450-c. 1150) is clearly a foreign language.
