4. Chaucer's English

Chaucer is sometimes considered the source of the English vernacular tradition and the "father" of modern English literature. His achievement for the language can be seen as part of a general historical trend towards the creation of a vernacular literature after the example of Dante in many parts of Europe. A parallel trend in Chaucer's own lifetime was underway in Scotland through the work of his slightly earlier contemporary, John Barbour, and was likely to have been even more general, as is evidenced by the example of the Pearl Poet in the north of England.

Geoffrey Chaucer (c. 1343 – 25 October 1400?) was an English author, poet, philosopher, bureaucrat, courtier and diplomat. Although he wrote many works, he is best remembered for his unfinished frame narrative The Canterbury Tales. Sometimes called the father of English literature, Chaucer is credited by some scholars as the first author to demonstrate the artistic legitimacy of the vernacular English language, rather than French or Latin.

Although Chaucer's language is much closer to modern English than the text of Beowulf, it differs enough that most publications modernise (and sometimes bowdlerise) his idiom. Following is a sample from the prologue of the "Summoner's Tale" that compares Chaucer's text to a modern translation.

Chaucer wrote in continental accentual-syllabic metre, a style which had developed since around the twelfth century as an alternative to the alliterative Anglo-Saxon metre. Chaucer is known for metrical innovation, inventing the rhyme royal, and he was one of the first English poets to use the five-stress line, a decasyllabic cousin to the iambic pentameter, in his work, with only a few anonymous short works using it before him. The arrangement of these five-stress lines into rhyming couplets, first seen in his Legend of Good Women, was used in much of his later work and became one of the standard poetic forms in English. His early influence as a satirist is also important, with the common humorous device, the funny accent of a regional dialect, apparently making its first appearance in The Reeve's Tale.

The poetry of Chaucer, along with other writers of the era, is credited with helping to standardize the London Dialect of the Middle English language from a combination of the Kentish and Midlands dialects. This is probably overstated; the influence of the court, chancery and bureaucracy—of which Chaucer was a part—remains a more probable influence on the development of Standard English. Modern English is somewhat distanced from the language of Chaucer's poems owing to the effect of the Great Vowel Shift some time after his death. This change in the pronunciation of English, still not fully understood, makes the reading of Chaucer difficult for the modern audience, though it is thought by some that the modern Scottish accent is closely related to the sound of Middle English. The status of the final -e in Chaucer's verse is uncertain: it seems likely that during the period of Chaucer's writing the final -e was dropping out of colloquial English and that its use was somewhat irregular. Chaucer's versification suggests that the final -e is sometimes to be vocalised, and sometimes to be silent; however, this remains a point on which there is disagreement. When it is vocalised, most scholars pronounce it as a schwa. Apart from the irregular spelling, much of the vocabulary is recognisable to the modern reader. Chaucer is also recorded in the Oxford English Dictionary as the first author to use many common English words in his writings. These words were probably frequently used in the language at the time but Chaucer, with his ear for common speech, is the earliest manuscript source. Acceptable, alkali, altercation, amble, angrily, annex, annoyance, approaching, arbitration, armless, army, arrogant, arsenic, arc, artillery and aspect are just some of those from the first letter of the alphabet.
