Mora (linguistics)A mora (plural morae or moras; often symbolized μ) is a basic timing unit in the phonology of some spoken languages, equal to or shorter than a syllable. For example, a short syllable such as ba consists of one mora (monomoraic), while a long syllable such as baa consists of two (bimoraic); extra-long syllables with three moras (trimoraic) are relatively rare. Such metrics are also referred to as syllable weight. The term comes from the Latin word for 'linger, delay', which was also used to translate the Greek word χρόνος : chrónos ('time') in its metrical sense.
Indo-European ablautIn linguistics, the Indo-European ablaut (ˈæblaʊt, from German Ablaut ˈaplaʊt) is a system of apophony (regular vowel variations) in the Proto-Indo-European language (PIE). An example of ablaut in English is the strong verb sing, sang, sung and its related noun song, a paradigm inherited directly from the Proto-Indo-European stage of the language. Traces of ablaut are found in all modern Indo-European languages, though its prevalence varies greatly.
Phonological history of English consonant clustersThe phonological history of the English language includes various changes in the phonology of consonant clusters. H-dropping The H-cluster reductions are various consonant reductions that have occurred in the history of English, involving consonant clusters beginning with /h/ that have lost the /h/ (or become reduced to /h/) in some or all dialects. Pronunciation of English ⟨wh⟩ The cluster /hw/ (spelled ⟨wh⟩ since Middle English) has been subject to two kinds of reduction: Reduction to /h/ before rounded vowels (due to /hw/ being perceived as a /h/ with the labialization characteristic of that environment).
DissimilationIn phonology, particularly within historical linguistics, dissimilation is a phenomenon whereby similar consonants or vowels in a word become less similar. In English, dissimilation is particularly common with liquid consonants such as /r/ and /l/ when they occur in a sequence. The phenomenon is often credited to horror aequi, the principle that language users avoid repetition of identical linguistic structures.
Vowel breakingIn historical linguistics, vowel breaking, vowel fracture, or diphthongization is the sound change of a monophthong into a diphthong or triphthong. Vowel breaking may be unconditioned or conditioned. It may be triggered by the presence of another sound, by stress, or in no particular way. Vowel breaking is sometimes defined as a subtype of diphthongization, when it refers to harmonic (assimilatory) process that involves diphthongization triggered by a following vowel or consonant.
AssibilationIn linguistics, assibilation is a sound change resulting in a sibilant consonant. It is a form of spirantization and is commonly the final phase of palatalization. A characteristic of Mashreqi varieties of Arabic (particularly Levantine and Egyptian) is to assibilate the interdental consonants of Modern Standard Arabic (MSA) in certain contexts (defined more culturally than phonotactically).
Accent (sociolinguistics)In sociolinguistics, an accent is a way of pronouncing a language that is distinctive to a country, area, social class, or individual. An accent may be identified with the locality in which its speakers reside (a regional or geographical accent), the socioeconomic status of its speakers, their ethnicity (an ethnolect), their caste or social class (a social accent), or influence from their first language (a foreign accent). Accents typically differ in quality of voice, pronunciation and distinction of vowels and consonants, stress, and prosody.
SchwaIn linguistics, specifically phonetics and phonology, schwa (ʃwɑː, rarely ʃwɔː or ʃvɑː; sometimes spelled shwa) is a vowel sound denoted by the IPA symbol ə, placed in the central position of the vowel chart. In English and some other languages, it usually represents the mid central vowel sound (rounded or unrounded), produced when the lips, tongue, and jaw are completely relaxed, such as the vowel sound of the a in the English word about.
Hiberno-EnglishHiberno-English (haɪ'bɜːrnoʊ_-,_hɪ-; from Latin Hibernia: "Ireland") or Irish English (IrE), also formerly Anglo-Irish, is the set of English dialects native to the island of Ireland (including both the Republic of Ireland and Northern Ireland). In the Republic of Ireland, English is one of two official languages, along with the Irish language, and is the country's de facto working language. Irish English's writing standards, such as its spelling, align with British English.
Japanese phonologyThe phonology of Japanese features about 15 consonant phonemes, the cross-linguistically typical five-vowel system of /a, e, i, o, u/, and a relatively simple phonotactic distribution of phonemes allowing few consonant clusters. It is traditionally described as having a mora as the unit of timing, with each mora taking up about the same length of time, so that the disyllabic [ɲip.poɴ] ("Japan") may be analyzed as /niQpoN/ and dissected into four moras, /ni/, /Q/, /po/, and /N/.
