In linguistics, "discontinuity" refers to a phenomenon where elements that are typically expected to be adjacent or in a contiguous structure are instead separated within a sentence or phrase. This can manifest in various ways, often involving grammatical constructions or syntactic movements that lead to gaps between related components. One common example of discontinuity occurs in the context of "discontinuous constituents," where elements that function together within the sentence are split apart, often by intervening phrases or clauses.

Differential Object Marking (DOM) is a linguistic phenomenon found in some languages where certain direct objects are marked with a special grammatical marker (often a case, preposition, or an article) based on specific semantic or pragmatic features. This typically involves distinguishing between different types of objects that may require different levels of attention or specificity from the speaker.

Differential argument marking (DAM) refers to a linguistic phenomenon where certain grammatical markers are employed to differentiate between various arguments of a verb based on specific semantic or syntactic criteria. This can occur within the framework of case marking, agreement, or other grammatical features, which indicate distinctions among participants in an action or state.

Diathesis alternation refers to the phenomenon in linguistics where a single verb can have different syntactic constructions or roles depending on the context, and this change alters the way participants in the action or state described by the verb are expressed. It often involves changes between active and passive voice, but can also include other variations such as causative constructions or intransitive usage. For example, consider the verb "break": 1. **Active Voice**: "The boy broke the vase.

Determiner spreading is a linguistic phenomenon observed in some languages, particularly in certain West African languages, where determiners (words that introduce nouns and provide information about their definiteness, quantity, etc.) can appear in a repeated or spread-out form. Instead of a single determiner introducing a noun phrase, multiple determiners can be used in conjunction with a noun or noun phrase.

A determiner phrase (DP) is a linguistic structure that serves as the nominal core of a sentence, often providing information about the noun it modifies.

Crossover effects refer to a phenomenon where the impact of an intervention, treatment, or variable observed in one group or context also influences another group or context, often in a different way than anticipated. This term can apply across various fields, including economics, psychology, marketing, and public health. For example: 1. **Marketing**: A marketing campaign targeted at one demographic may inadvertently influence another demographic, leading to a crossover effect where sales increase in both groups.

Coreference is a linguistic phenomenon in which two or more expressions in a text refer to the same entity or individual. For example, in the sentences "Lisa went to the store. She bought some groceries," the pronoun "she" is a coreferential expression that refers back to "Lisa.

In linguistics, coordination refers to the grammatical and syntactic process of linking two or more elements of equal status within a sentence. These elements can include words, phrases, or clauses. Coordination is typically achieved through coordinating conjunctions (also known as coordinators), the most common of which are "and," "but," and "or.

A content clause, often referred to as a "complement clause," is a type of subordinate clause that serves as the complement to a verb, adjective, or noun within a sentence. It provides specific information about the action or state described by the main clause. Content clauses typically begin with words like "that," "if," or "whether." For example: 1. "She said **that** she would come to the party.

In linguistics, a "constituent" refers to a word or a group of words that function as a single unit within a hierarchical structure of a sentence. Constituents can be phrases or even individual words that can serve as subjects, objects, or complements in a sentence. The study of constituents is fundamental in syntax, which examines how words combine to create phrases and sentences.

Consonant mutation, also known as consonant shift or consonantal mutation, refers to a phonological phenomenon in which consonants change their articulatory properties based on their phonetic environment or the grammatical context in which they occur. This can involve changes in voicing, place of articulation, or manner of articulation.

In linguistics, a "compound" refers to a word that is formed by combining two or more independent words, which come together to create a new word with a distinct meaning. Compounds are a common feature in many languages and can take various forms. There are typically three types of compounds: 1. **Closed Compounds**: These are written as a single word with no spaces or hyphens, such as "toothbrush," "notebook," and "basketball.

Comparative illusion is a psychological concept that refers to the tendency of individuals to perceive themselves, their abilities, or their situations as better than those of others, often based on subjective comparisons. This can occur in various domains, such as intelligence, physical attractiveness, or social skills, where people may overestimate their standing relative to their peers.

In linguistics, coherence refers to the overall sense and clarity of meaning in a text or discourse. It is a crucial aspect of text organization that helps ensure that the ideas presented are logically connected and understandable to the reader or listener. Coherence allows pieces of information within a text to relate to each other in a way that makes sense, enabling the audience to follow the argument or narrative as intended.

Code-mixing is a linguistic phenomenon where speakers alternate between two or more languages or language varieties within a single conversation, sentence, or discourse. This can occur in various contexts, such as informal conversations among bilingual or multilingual speakers. Code-mixing often reflects the speaker's cultural identity, social context, and emotional state, allowing for nuanced expression that may not be possible in a single language.

Clitic climbing is a linguistic phenomenon that occurs in certain languages where a clitic, which is a type of morpheme that behaves like a word but cannot stand alone (such as contractions or auxiliary verbs in English), can "climb" over another element in a sentence to attach to a different position, typically a higher one, than its original position.

A clitic is a linguistic unit that has characteristics of both a word and a morpheme. It is a form that cannot stand alone as a separate word and must attach to another word (usually a host) to convey meaning. Clitics often serve grammatical functions, such as indicating possession, conjunction, or tense. Clitics can be classified into two main types: 1. **Proclitic**: A clitic that attaches to the beginning of a host word.

In linguistics, "catena" refers to a sequence of words that functions as a meaningful unit within a sentence, even if that sequence does not correspond to a traditional syntactic constituent like a phrase or clause. The term is often used in the context of dependency grammar or construction grammar, where the relationships between words are highlighted. A catena can be formed by words that are connected through dependency relationships, rather than being contiguous in the syntactic structure.

C-command is a syntactic concept used in linguistic theory, particularly in the fields of generative grammar and semantics. The notion was introduced by Noam Chomsky and is crucial for understanding various syntactic phenomena, particularly in relation to binding, reflexivity, and sentence structure.
