A diphthong (/ ˈ d ɪ f θ ɒ ŋ, ˈ d ɪ p-/ DIF-thong, DIP-; [1] from Ancient Greek δίφθογγος (díphthongos) 'two sounds', from δίς (dís) 'twice' and φθόγγος (phthóngos) 'sound'), also known as a gliding vowel or a vowel glide, is a combination of two adjacent vowel sounds within the same syllable. [2]
A short diphthong had the same length as a short single vowel, and a long diphthong had the same length as a long single vowel. [124] As with monophthongs, their length was not systematically marked in Old English manuscripts, but is inferred from other evidence, such as a word's etymological origins or the pronunciation of its descendants.
In an unstressed open syllable, /i/ and /u/ (including final /-u/ from earlier /-oː/) were lost when following a long syllable (i.e. one with a long vowel or diphthong, or followed by two consonants), but not when following a short syllable (i.e. one with a short vowel followed by a single consonant). [21] This took place in two types of contexts:
A vowel sound that glides from one quality to another is called a diphthong, and a vowel sound that glides successively through three qualities is a triphthong. All languages have monophthongs and many languages have diphthongs, but triphthongs or vowel sounds with even more target qualities are relatively rare cross-linguistically.
Although the Old English diphthongs merged into monophthongs, Middle English began to develop a new set of diphthongs.Many of these came about through vocalization of the palatal approximant /j/ (usually from an earlier /ʝ/) or the labio-velar approximant /w/ (sometimes from an earlier voiced velar fricative [ɣ]), when they followed a vowel.
A syllable ending in a short vowel, or the diphthongs αι and οι in certain noun and verb endings, was light. All other syllables were heavy: that is, syllables ending in a long vowel or diphthong, a short vowel and consonant, or a long vowel or diphthong and consonant. λέγω /lé.ɡɔɔ/: light – heavy;
The vowel /ə/ is often pronounced [ɐ] in open syllables. [67] The PRICE and MOUTH diphthongs may be pronounced with a less open starting point when followed by a voiceless consonant; [68] this is chiefly a feature of Canadian speech (Canadian raising), but is also found in parts of the United States. [69]
In the transition to Middle English, the system underwent major changes by eliminating the diphthongs and leaving only one pair of low vowels but with a vowel distinction appearing in the long mid vowels: The diphthongs /æɑ̯/ /æːɑ̯/ simplified to /æ/ and /æː/, respectively. Subsequently, the low vowels were modified as follows:
