In grammar, tense is a category that expresses time reference. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns.
Infinitive is a linguistics term for certain verb forms existing in many languages, most often used as non-finite verbs. As with many linguistic concepts, there is not a single definition applicable to all languages. The name is derived from Late Latin [modus] infinitivus, a derivative of infinitus meaning "unlimited".
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.
The imperative mood is a grammatical mood that forms a command or request.
The preterite or preterit is a grammatical tense or verb form serving to denote events that took place or were completed in the past; in some languages, such as Spanish, French, and English, it is equivalent to the simple past tense. In general, it combines the perfective aspect with the past tense and may thus also be termed the perfective past. In grammars of particular languages the preterite is sometimes called the past historic, or the aorist. When the term "preterite" is used in relation to specific languages, it may not correspond precisely to this definition. In English it can be used to refer to the simple past verb form, which sometimes expresses perfective aspect. The case of German is similar: the Präteritum is the simple (non-compound) past tense, which does not always imply perfective aspect, and is anyway often replaced by the Perfekt even in perfective past meanings.
The subjunctive is a grammatical mood, a feature of an utterance that indicates the speaker's attitude toward it. Subjunctive forms of verbs are typically used to express various states of unreality such as wish, emotion, possibility, judgment, opinion, obligation, or action that has not yet occurred; the precise situations in which they are used vary from language to language. The subjunctive is one of the irrealis moods, which refer to what is not necessarily real. It is often contrasted with the indicative, a realis mood which principally indicates that something is a statement of fact.
In grammar, a future tense is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French aimera, meaning "will love", derived from the verb aimer ("love"). The "future" expressed by the future tense usually means the future relative to the moment of speaking, although in contexts where relative tense is used it may mean the future relative to some other point in time under consideration.
Spanish verbs form one of the more complex areas of Spanish grammar. Spanish is a relatively synthetic language with a moderate to high degree of inflection, which shows up mostly in Spanish conjugation.
The perfect tense or aspect is a verb form that indicates that an action or circumstance occurred earlier than the time under consideration, often focusing attention on the resulting state rather than on the occurrence itself. An example of a perfect construction is I have made dinner. Although this gives information about a prior action, the focus is likely to be on the present consequences of that action. The word perfect in this sense means "completed".
The continuous and progressive aspects are grammatical aspects that express incomplete action or state in progress at a specific time: they are non-habitual, imperfective aspects.
The imperfect is a verb form that combines past tense and imperfective aspect. It can have meanings similar to the English "was walking" or "used to walk". It contrasts with preterite forms, which refer to a single completed event in the past.
In French grammar, verbs are a part of speech. Each verb lexeme has a collection of finite and non-finite forms in its conjugation scheme.
The simple present, present simple or present indefinite is one of the verb forms associated with the present tense in modern English. It is commonly referred to as a tense, although it also encodes certain information about aspect in addition to the present time. The simple present is the most commonly used verb form in English, accounting for more than half of verbs in spoken English.
The conditional mood is a grammatical mood used in conditional sentences to express a proposition whose validity is dependent on some condition, possibly counterfactual.
In linguistics, grammatical mood is a grammatical feature of verbs, used for signaling modality. That is, it is the use of verbal inflections that allow speakers to express their attitude toward what they are saying. The term is also used more broadly to describe the syntactic expression of modality – that is, the use of verb phrases that do not involve inflection of the verb itself.
Tense–aspect–mood or tense–modality–aspect is a group of grammatical categories that are important to understanding spoken or written content, and which are marked in different ways by different languages.
This article discusses the conjugation of verbs in a number of varieties of Catalan, including Old Catalan. Each verbal form is accompanied by its phonetic transcription. Widely used dialectal forms are included, even if they are not considered standard in either of the written norms: those of the Institut d'Estudis Catalans and the Acadèmia Valenciana de la Llengua. Other dialectal forms exist, including those characteristic of minor dialects such as Ribagorçan and Algherese and transitional forms of major dialects.
Portuguese verbs display a high degree of inflection. A typical regular verb has over fifty different forms, expressing up to six different grammatical tenses and three moods. Two forms are peculiar to Portuguese within the Romance languages:
This article describes the uses of various verb forms in modern standard English language. This includes:
Hindustani verbs conjugate according to mood, tense, person and number. Hindustani inflection is markedly simpler in comparison to Sanskrit, from which Hindustani has inherited its verbal conjugation system. Aspect-marking participles in Hindustani mark the aspect. Gender is not distinct in the present tense of the indicative mood, but all the participle forms agree with the gender and number of the subject. Verbs agree with the gender of the subject or the object depending on whether the subject pronoun is in the dative or ergative case or the nominative case.
