Nonconcatenative morphologyNonconcatenative morphology, also called discontinuous morphology and introflection, is a form of word formation and inflection in which the root is modified and which does not involve stringing morphemes together sequentially. Apophony Ablaut and Umlaut (linguistics) In English, for example, while plurals are usually formed by adding the suffix -s, certain words use nonconcatenative processes for their plural forms: foot /fʊt/ → feet /fiːt/; Many irregular verbs form their past tenses, past participles, or both in this manner: freeze /ˈfriːz/ → froze /ˈfroʊz/, frozen /ˈfroʊzən/.
CausativeIn linguistics, a causative (abbreviated ) is a valency-increasing operation that indicates that a subject either causes someone or something else to do or be something or causes a change in state of a non-volitional event. Normally, it brings in a new argument (the causer), A, into a transitive clause, with the original subject S becoming the object O. All languages have ways to express causation but differ in the means. Most, if not all, languages have specific or lexical causative forms (such as English rise → raise, lie → lay, sit → set).
Moroccan ArabicMoroccan Arabic (العربية المغربية الدارجة Moroccan vernacular Arabic), also known as Darija (الدارجة), is the dialectal, vernacular form or forms of Arabic spoken in Morocco. It is part of the Maghrebi Arabic dialect continuum and as such is mutually intelligible to some extent with Algerian Arabic and to a lesser extent with Tunisian Arabic. It is spoken by 90.9% of the population of Morocco.
ApophonyIn linguistics, apophony (also known as ablaut, (vowel) gradation, (vowel) mutation, alternation, internal modification, stem modification, stem alternation, replacive morphology, stem mutation, internal inflection etc.) is any alternation within a word that indicates grammatical information (often inflectional). Apophony is exemplified in English as the internal vowel alternations that produce such related words as sng, sng, sng, sng bnd, bnd bld, bld brd, brd dm, dm fd, fd l, l rse, rse, rsen wve, wve ft, ft gse, gse tth, tth The difference in these vowels marks variously a difference in tense or aspect (e.
Lemma (morphology)In morphology and lexicography, a lemma (: lemmas or lemmata) is the canonical form, dictionary form, or citation form of a set of word forms. In English, for example, break, breaks, broke, broken and breaking are forms of the same lexeme, with break as the lemma by which they are indexed. Lexeme, in this context, refers to the set of all the inflected or alternating forms in the paradigm of a single word, and lemma refers to the particular form that is chosen by convention to represent the lexeme.
Varieties of ArabicThe varieties (or dialects or vernacular languages) of Arabic, a Semitic language within the Afroasiatic family originating in the Arabian Peninsula, are the linguistic systems that Arabic speakers speak natively. There are considerable variations from region to region, with degrees of mutual intelligibility that are often related to geographical distance and some that are mutually unintelligible. Many aspects of the variability attested to in these modern variants can be found in the ancient Arabic dialects in the peninsula.
