Phonological history of English close front vowelsThe close and mid-height front vowels of English (vowels of i and e type) have undergone a variety of changes over time and often vary by dialect. Middle English had a long close front vowel /iː/, and two long mid front vowels: the close-mid /eː/ and the open-mid /ɛː/. The three vowels generally correspond to the modern spellings , and respectively, but other spellings are also possible. The spellings that became established in Early Modern English are mostly still used today, but the qualities of the sounds have changed significantly.
Pronunciation of English ⟨wh⟩The pronunciation of the digraph in English has changed over time, and still varies today between different regions and accents. It is now most commonly pronounced /w/, the same as a plain initial , although some dialects, particularly those of Scotland, Ireland, and the Southern United States, retain the traditional pronunciation /hw/, generally realized as ʍ, a voiceless "w" sound. The process by which the historical /hw/ has become /w/ in most modern varieties of English is called the wine–whine merger.
FlappingFlapping or tapping, also known as alveolar flapping, intervocalic flapping, or t-voicing, is a phonological process found in many varieties of English, especially North American, Cardiff, Ulster, Australian and New Zealand English, whereby the voiceless alveolar stop consonant phoneme t is pronounced as a voiced alveolar flap [ɾ], a sound produced by briefly tapping the alveolar ridge with the tongue, when placed between vowels. In London English, the flapped ɾ is perceived as a casual pronunciation intermediate between the "posh" affricate ts and the "rough" glottal stop ʔ.
Phonological changeIn historical linguistics, phonological change is any sound change that alters the distribution of phonemes in a language. In other words, a language develops a new system of oppositions among its phonemes. Old contrasts may disappear, new ones may emerge, or they may simply be rearranged. Sound change may be an impetus for changes in the phonological structures of a language (and likewise, phonological change may sway the process of sound change).
AbbreviationAn abbreviation (from Latin brevis, meaning short) is a shortened form of a word or phrase, by any method. It may consist of a group of letters or words taken from the full version of the word or phrase; for example, the word abbreviation can itself be represented by the abbreviation abbr., abbrv., or abbrev.; NPO, for nil (or nothing) per (by) os (mouth) is an abbreviated medical instruction. It may also consist of initials only, a mixture of initials and words, or words or letters representing words in another language (for example, e.
Cot–caught mergerThe cot–caught merger, also known as the merger or low back merger, is a sound change present in some dialects of English where speakers do not distinguish the vowel phonemes in words like cot versus caught. Cot and caught (along with bot and bought, pond and pawned, etc.) is an example of a minimal pair that is lost as a result of this sound change. The phonemes involved in the cot–caught merger, the low back vowels, are typically represented in the International Phonetic Alphabet as /ɒ/ and /ɔ/, respectively (or, in North America, co-occurring with the father–bother merger, as /ɑ/ and /ɔ/).
English language in EnglandThe English language spoken and written in England encompasses a diverse range of accents and dialects. The language forms part of the broader British English, along with other varieties in the United Kingdom. Terms used to refer to the English language spoken and written in England include: English English and Anglo-English.
TensenessIn phonology, tenseness or tensing is, most broadly, the pronunciation of a sound with greater muscular effort or constriction than is typical. More specifically, tenseness is the pronunciation of a vowel with less centralization (i.e. either more fronting or more backing), longer duration, and narrower mouth width (with the tongue being perhaps more raised) compared with another vowel. The opposite quality to tenseness is known as laxness or laxing: the pronunciation of a vowel with relatively more centralization, shorter duration, and more widening (perhaps even lowering).
Lexical setA lexical set is a group of words that share a particular phonological feature. A phoneme is a basic unit of sound in a language that can distinguish one word from another. Most commonly, following the work of phonetician John C. Wells, a lexical set is a class of words in a language that share a certain vowel phoneme. As Wells himself says, lexical sets "enable one to refer concisely to large groups of words which tend to share the same vowel, and to the vowel which they share".
Free variationIn linguistics, free variation is the phenomenon of two (or more) sounds or forms appearing in the same environment without a change in meaning and without being considered incorrect by native speakers. Sociolinguists argue that describing such variation as "free" is very often a misnomer, since variation between linguistic forms is usually constrained probabilistically by a range of systematic social and linguistic factors, not unconstrained as the term "free variation" suggests.
