SuprafixIn linguistics, a suprafix is a type of affix that gives a suprasegmental pattern (such as tone, stress, or nasalization) to either a neutral base or a base with a preexisting suprasegmental pattern. This affix will, then, convey a derivational or inflectional meaning. This suprasegmental pattern acts like segmental phonemes within a morpheme; the suprafix is a combination of suprasegmental phonemes, organized into a pattern, that creates a morpheme. For example, a number of African languages express tenseaspect distinctions by tone.
WordA word is a basic element of language that carries an objective or practical meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition.
Consonant gradationConsonant gradation is a type of consonant mutation (mostly lenition but also assimilation) found in some Uralic languages, more specifically in the Finnic, Samic and Samoyedic branches. It originally arose as an allophonic alternation between open and closed syllables, but has become grammaticalised due to changes in the syllable structure of the languages affected. The term "consonant gradation" refers to a word-medial alternation of consonants between fortis and lenis realisations.
Berber languagesThe Berber languages, also known as the Amazigh languages or Tamazight, are a branch of the Afroasiatic language family. They comprise a group of closely related but mostly mutually unintelligible languages spoken by Berber communities, who are indigenous to North Africa. The languages are primarily spoken and not typically written. Historically, they have been written with the ancient Libyco-Berber script, which now exists in the form of Tifinagh.
Vowel harmonyIn phonology, vowel harmony is an assimilatory process in which the vowels of a given domain – typically a phonological word – have to be members of the same natural class (thus "in harmony"). Vowel harmony is typically long distance, meaning that the affected vowels do not need to be immediately adjacent, and there can be intervening segments between the affected vowels. Generally one vowel will trigger a shift in other vowels, either progressively or regressively, within the domain, such that the affected vowels match the relevant feature of the trigger vowel.
Fusional languageFusional languages or inflected languages are a type of synthetic language, distinguished from agglutinative languages by their tendency to use a single inflectional morpheme to denote multiple grammatical, syntactic, or semantic features. For example, the Spanish verb comer ("to eat") has the first-person singular preterite tense form comí ("I ate"); the single suffix -í represents both the features of first-person singular agreement and preterite tense, instead of having a separate affix for each feature.
