The
surface sounds of Chaucer's Middle English (whether
allophones or
phonemes) are shown in the tables below. Phonemes in
bold were added across Middle English; those in
italics were removed during the period.
Consonants 1. The exact nature of Middle English
r is unknown. This article uses indiscriminately.
Consonant allophones The sounds marked in parentheses in the table above are allophones: • is an allophone of occurring before and • For example, () is ; did not occur alone in Middle English, unlike in Modern English. • are allophones of in syllable-final position after
front and
back vowels, respectively. • Based on evidence from
Old English and
Modern English, and apparently had velarised counterparts or allophones and . These occurred after back vowels or the consonant .
Voiced fricatives In Old English, , , were allophones of , , , respectively, occurring between
vowels or
voiced consonants. That led to many alternations: () vs. () ; () vs. () . In Middle English, voiced allophones become phonemes and have become solidly established in Modern English as separate phonemes by several sources: • Borrowings from foreign languages, especially
Latin,
Ancient Greek and
Old French, which introduced sounds where they had not occurred: modern
fine vs.
vine (both borrowings from French);
ether (from Greek) vs.
either (native). • Dialect mixture between Old English dialects (like
Kentish) that voiced initial fricatives and the more standard dialects that did not. Compare
fat vs.
vat (both with
f- in standard
Old English) and
fox vs.
vixen (
Old English fox vs.
fyxen, from
Proto-Germanic vs. ). • Analogical changes that levelled former alternations:
grass, grasses, grassy and
glass, glasses, glassy with replacing the original between vowels (but
to graze and
to glaze, still with , originally derived from
grass and
glass, respectively). Contrast
wife vs.
wives;
greasy, still with a in some dialects (such as
Southern American English) and
staff, with two plurals, analogical
staffs and inherited
staves. • Loss of final , resulting in voiced fricatives at the end of a word where only voiceless fricatives had occurred. That is the source of the modern distinctions
teeth vs.
to teethe,
half vs.
to halve,
house vs.
to house. • Reduction of double consonants to single consonants, which explains the contrast between
kiss, to kiss (Old English
coss, cyssan, with a double
s) vs.
house, to house with in the verb (Old English , with a single
s). • A
sandhi that introduced the voiced fricative /ð/, instead of original /θ/, at the beginning of unstressed function words. Contrast
this with initial vs.
thistle with initial . • A sound change that caused fricatives to be voiced after a fully unstressed syllable. That is reflected in the modern pronunciation of the endings that are spelled
-s (the noun plural ending, the '
Saxon genitive' ending and the third-person present indicative ending), which now have the phonemic shape -, having developed in Middle English from - to - and then, after the deletion of the unstressed vowel, to - (e.g.
halls,
tells from earlier
halles,
telles). The sound change also affects function words ending in original - that are normally unstressed. Contrast
this with vs.
is with ;
off with vs.
of with , originally the same word;
with with in many varieties of English vs.
pith with . The status of the sources in Chaucer's Middle English is as follows: • The first three sources (borrowing, dialect mixture and analogy) were already established. • As indicated by versification, the loss of final was normal in Chaucer's time before a vowel-initial word and optional elsewhere. That is assumed to be a poetic relic, with the loss of final having been completed in spoken English (a similar situation to Modern French; see
e muet). • The reduction of double consonants was apparently about to occur. • The sandhi effects on unstressed function words occurred somewhat later, during the transition to Modern English. The strongest distinction was between and because of the large number of borrowings from
Old French. It is also the only distinction that is consistently indicated in spelling, as and respectively. sometimes appears as , especially in borrowings from Greek and sometimes as . Both and are spelled .
Vowels 1 The Old English sequences , produced late Middle English and had apparently passed through early Middle English : OE
grōwan ('grow') → LME . However, early Middle English that was produced by
Middle English breaking became late Middle English : OE
tōh (tough') → EME → LME . Apparently, early became before the occurrence of Middle English breaking, which generated new occurrences of , which later became .
Monophthongs Middle English had a distinction between
close-mid and
open-mid long vowels but no corresponding distinction in short vowels. The behaviour of
open syllable lengthening seems to indicate that the short vowels were open-mid in quality, but according to Lass, they were close-mid. (There is some direct documentary evidence: in early texts, open-mid was spelled , but both and were spelled .) Later, the short vowels were in fact lowered to become open-mid vowels, as is shown by their values in Modern English. The
front rounded vowels existed in the southwest dialects of Middle English, which developed from the standard
Late West Saxon dialect of
Old English, but not in the standard Middle English dialect of London. The close vowels and are direct descendants of the corresponding Old English vowels and were indicated as . (In the standard dialect of Middle English, the sounds became and ; in
Kentish, they became and .) may have existed in learned speech in loanwords from Old French, also spelled , but, as it merged with , becoming in Modern English, rather than , it can be assumed that was the vernacular pronunciation that was used in French-derived words. The mid-front rounded vowels likewise had existed in the southwest dialects but not in the standard Middle English dialect of London and were indicated as . Sometime in the 13th century, they became unrounded and merged with the normal front mid vowels. They derived from the
Old English diphthongs and . There is no direct evidence that there was ever a distinction between open-mid and close-mid , but it can be assumed because of the corresponding distinction in the unrounded mid front vowels. would have derived directly from
Old English , and derived from the open syllable lengthening of short , from the Old English short diphthong . The quality of the short open vowel is unclear. In early Middle English, it was presumably central since it represented the coalescence of the Old English vowels and . During
Middle English breaking, it could not have been a front vowel since rather than was introduced after it. During Early Modern English, it was fronted in most environments to in southern England, and it and even closer values are found in the contemporary speech of southern England, North America and the Southern Hemisphere. It remains in much of Northern England, Scotland and the Caribbean. Meanwhile, the long open vowel, which developed later because of open syllable lengthening, was . It was gradually fronted, to successively , and , in the 16th and the 17th centuries.
Diphthongs All of the above diphthongs came about during the Middle English. Old English had a number of diphthongs, but all of them had been reduced to monophthongs in the transition to Middle English. Diphthongs in Middle English came about by various processes and at various time periods and tended to change their quality over time. The changes above occurred mostly between early and late Middle English. Early Middle English had a distinction between
open-mid and
close-mid diphthongs, and all of the close-mid diphthongs had been eliminated by late Middle English. The following processes produced the above diphthongs: • Reinterpretation of Old English sequences of a vowel followed by Old English (which became after back vowels and after front vowels) or with pre-existing , : • OE
weġ ('way') → EME • OE
dæġ ('day') → ME → LME • Middle English breaking before ( after
back vowels, after
front vowels) • Borrowing, especially from
