A passive voice construction is a grammatical voice construction that is found in many languages. In a clause with passive voice, the grammatical subject expresses the theme or patient of the main verb – that is, the person or thing that undergoes the action or has its state changed. This contrasts with active voice, in which the subject has the agent role. For example, in the passive sentence "The tree was pulled down", the subject denotes the patient rather than the agent of the action. In contrast, the sentences "Someone pulled down the tree" and "The tree is down" are active sentences.
A verb is a word that in syntax generally conveys an action, an occurrence, or a state of being. In the usual description of English, the basic form, with or without the particle to, is the infinitive. In many languages, verbs are inflected to encode tense, aspect, mood, and voice. A verb may also agree with the person, gender or number of some of its arguments, such as its subject, or object. Verbs have tenses: present, to indicate that an action is being carried out; past, to indicate that an action has been done; future, to indicate that an action will be done.
In grammar, an intransitive verb is a verb whose context does not entail a direct object. That lack of transitivity distinguishes intransitive verbs from transitive verbs, which entail one or more objects. Additionally, intransitive verbs are typically considered within a class apart from modal verbs and defective verbs.
Lexical semantics, as a subfield of linguistic semantics, is the study of word meanings. It includes the study of how words structure their meaning, how they act in grammar and compositionality, and the relationships between the distinct senses and uses of a word.
In general linguistics, a labile verb is a verb that undergoes causative alternation; that is, it can be used both transitively and intransitively, with the requirement that the direct object of its transitive use corresponds to the subject of its intransitive use, as in "I ring the bell" and "The bell rings." Labile verbs are a prominent feature of English, but they also occur in many other languages. When causatively alternating verbs are used transitively they are called causatives since, in the transitive use of the verb, the subject is causing the action denoted by the intransitive version. When causatively alternating verbs are used intransitively, they are referred to as anticausatives or inchoatives because the intransitive variant describes a situation in which the theme participant undergoes a change of state, becoming, for example, "opened".
In linguistic typology, split ergativity is a feature of certain languages where some constructions use ergative syntax and morphology, but other constructions show another pattern, usually nominative–accusative. The conditions in which ergative constructions are used vary among different languages.
In linguistic typology, ergative–absolutive alignment is a type of morphosyntactic alignment in which the single argument ("subject") of an intransitive verb behaves like the object of a transitive verb, and differently from the agent of a transitive verb. Examples include Basque, Georgian, Mayan, Tibetan, and certain Indo-European languages. It has also been attributed to the Semitic modern Aramaic languages. Ergative languages are classified into 2 groups: those that are morphologically ergative but syntactically behave as accusative and those that—on top of being ergative morphologically—also show ergativity in syntax. No language has been recorded in which both the morphological and syntactical ergative are present. Languages that belong to the former group are more numerous than those to the latter. Dyirbal is said to be the only representative of syntactic ergativity, yet it displays accusative alignment with certain pronouns.
In linguistic typology, nominative–accusative alignment is a type of morphosyntactic alignment in which subjects of intransitive verbs are treated like subjects of transitive verbs, and are distinguished from objects of transitive verbs in basic clause constructions. Nominative–accusative alignment can be coded by case-marking, verb agreement and/or word order. It has a wide global distribution and is the most common alignment system among the world's languages. Languages with nominative–accusative alignment are commonly called nominative–accusative languages.
In linguistic typology, tripartite alignment is a type of morphosyntactic alignment in which the main argument ('subject') of an intransitive verb, the agent argument ('subject') of a transitive verb, and the patient argument of a transitive verb are each treated distinctly in the grammatical system of a language. This is in contrast with nominative-accusative and ergative-absolutive alignment languages, in which the argument of an intransitive verb patterns with either the agent argument of the transitive or with the patient argument of the transitive. Thus, whereas in English, "she" in "she runs" patterns with "she" in "she finds it", and an ergative language would pattern "she" in "she runs" with "her" in "he likes her", a tripartite language would treat the "she" in "she runs" as morphologically and/or syntactically distinct from either argument in "he likes her".
Georgian grammar has many distinctive and extremely complex features, such as split ergativity and a polypersonal verb agreement system.
An unergative verb is an intransitive verb that is characterized semantically by having a subject argument which is an agent that actively initiates the action expressed by the verb.
An ambitransitive verb is a verb that is both intransitive and transitive. This verb may or may not require a direct object. English has many ambitransitive verbs. Examples include read, break, and understand.
The impersonal passive voice is a verb voice that decreases the valency of an intransitive verb to zero.
Hindustani, the lingua franca of Northern India and Pakistan, has two standardised registers: Hindi and Urdu. Grammatical differences between the two standards are minor but each uses its own script: Hindi uses Devanagari while Urdu uses an extended form of the Perso-Arabic script, typically in the Nastaʿlīq style.
In linguistics, volition is a concept that distinguishes whether the subject, or agent of a particular sentence intended an action or not. Simply, it is the intentional or unintentional nature of an action. Volition concerns the idea of control and for the purposes outside of psychology and cognitive science, is considered the same as intention in linguistics. Volition can then be expressed in a given language using a variety of possible methods. These sentence forms usually indicate that a given action has been done intentionally, or willingly. There are various ways of marking volition cross-linguistically. When using verbs of volition in English, like "want" or "prefer", these verbs are not expressly marked. Other languages handle this with affixes, while others have complex structural consequences of volitional or non-volitional encoding.
In linguistics, transitivity is a property of verbs that relates to whether a verb can take objects and how many such objects a verb can take. It is closely related to valency, which considers other verb arguments in addition to direct objects. The obligatory noun phrases and prepositional phrases determine how many arguments a predicate has. Obligatory elements are considered arguments while optional ones are never counted in the list of arguments.
The grammar of the Marathi language shares similarities with other modern Indo-Aryan languages such as Odia, Gujarati or Punjabi. The first modern book exclusively about the grammar of Marathi was printed in 1805 by Willam Carey.
Guanano (Wanano), or Piratapuyo, is a Tucanoan language spoken in the northwest part of Amazonas in Brazil and in Vaupés in Colombia. It is spoken by two peoples, the Wanano and the Piratapuyo. They do not intermarry, but their speech is 75% lexically similar.
Kʼicheʼ, or Quiché, is a Mayan language of Guatemala, spoken by the Kʼicheʼ people of the central highlands. With over a million speakers, Kʼicheʼ is the second most widely-spoken language in the country, after Spanish. It is one of the most widely-spoken indigenous American languages in Mesoamerica.
In generative linguistics, Burzio's generalization is the observation that a verb can assign a theta role to its subject position if and only if it can assign an accusative case to its object. Accordingly, if a verb does not assign a theta role to its subject, then it does not assign accusative case to its object. The generalization is named after Italian linguist Luigi Burzio, based on work published in the 1980s, but the seeds of the idea are found in earlier scholarship. The generalization can be logically written in the following equation:
θ ↔ A Where: θ = Subject Theta Role A = Accusative Case
