Apheresis (linguistics)In phonetics and phonology, apheresis (əˈfɛrɪsɪs,_əˈfɪərɪsɪs; aphaeresis) is a sound change in which a word-initial vowel is lost, e.g., American > 'Merican. In a broader sense, it can refer to the loss of any initial sound (including consonants) from a word or, in a less technical sense, to the loss of one or more sounds from the beginning of a word. The more specific term aphesis (and its adjective aphetic) is sometimes used to refer to the loss of unstressed vowels.
Syncope (phonology)In phonology, syncope (ˈsɪŋkəpi; from ) is the loss of one or more sounds from the interior of a word, especially the loss of an unstressed vowel. It is found in both synchronic and diachronic analyses of languages. Its opposite, whereby sounds are added, is epenthesis. Synchronic analysis studies linguistic phenomena at one moment of a language's history, usually the present, in contrast to diachronic analysis, which studies a language's states and the patterns of change across a historical timeframe.
Contraction (grammar)A contraction is a shortened version of the spoken and written forms of a word, syllable, or word group, created by omission of internal letters and sounds. In linguistic analysis, contractions should not be confused with crasis, abbreviations and initialisms (including acronyms), with which they share some semantic and phonetic functions, though all three are connoted by the term "abbreviation" in layman’s terms. Contraction is also distinguished from morphological clipping, where beginnings and endings are omitted.
ElisionIn linguistics, an elision or deletion is the omission of one or more sounds (such as a vowel, a consonant, or a whole syllable) in a word or phrase. However, these terms are also used to refer more narrowly to cases where two words are run together by the omission of a final sound. An example is the elision of word-final /t/ in English if it is preceded and followed by a consonant: "first light" is often pronounced /fɜ:s laɪt/. Many other terms are used to refer to specific cases where sounds are omitted.
