Present tense in the context of English verbs

A verb is a word that generally conveys an action (bring, read, walk, run, learn), an occurrence (happen, become), or a state of being (be, exist, stand). In the usual description of English, the basic form, with or without the particle to, is the infinitive. In many languages, verbs are inflected (modified in form) 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. In English, three tenses exist: present, to indicate that an action is being carried out; past, to indicate that an action has been done; and future, to indicate that an action will be done, expressed with the auxiliary verb will or shall.

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.

The main tenses found in many languages include the past, present, and future. Some languages have only two distinct tenses, such as past and nonpast, or future and nonfuture, while some languages make finer tense distinctions, such as remote vs recent past, or near vs remote future. There are also tenseless languages, like most of the Chinese languages, however, these languages do refer to time in different ways.

In grammar, a future tense (abbreviated FUT) 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 achètera, meaning "will buy", derived from the verb acheter ("to buy"). 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.

English does not have an inflectional future tense, though it has a variety of grammatical and lexical means for expressing future-related meanings. These include modal auxiliaries such as will and shall as well as the futurate present tense.

Ego eimi (Ancient Greek: ἐγώ εἰμι [eɡɔ̌ː eːmí]) "I am", "I exist", is the first person singular present active indicative of the verb "to be" in ancient Greek. The use of this phrase in some of the uses found in the Gospel of John (particularly in John 8:58) is considered to have theological significance by many Christians.

Verbs constitute one of the main parts of speech (word classes) in the English language. Like other types of words in the language, English verbs are not heavily inflected. Most combinations of tense, aspect, mood and voice are expressed periphrastically, using constructions with auxiliary verbs.

Generally, the only inflected forms of an English verb are a third person singular present tense form ending in -s, a past tense (also called preterite), a past participle (which may be the same as the past tense), and a form ending in -ing that serves as a present participle and gerund. Most verbs inflect in a simple regular fashion, although there are about 200 irregular verbs; the irregularity in nearly all cases concerns the past tense and past participle forms. The copula verb be has a larger number of different inflected forms, and is highly irregular.

The nonpast tense (also spelled non-past) (abbreviated NPST) is a grammatical tense that distinguishes an action as taking place in times present or future. The nonpast tense contrasts with the past tense, which distinguishes an action as taking place prior to the moment of utterance.

The nonpast tense is observed in many languages. Due to a lack of future tense inflectional morphology on the verb stem, many languages that are popularly conceived as having a three-way tense distinction (between past, present, and future), can in fact be understood as having a two-way past-nonpast tense distinction. For example, in English, future sentences often take present tense verb morphology, and do not contain specialized future tense verb morphology. In contrast, past tense sentences require specialized past tense morphology. Compares for instance the sentence: I hope he gets [nonpast] better tomorrow (in which the main verb gets is conjugated in the present tense, and the future is indicated lexically through the word tomorrow), and the sentence I hope he got [past] better yesterday (which requires the use of a specialized past tense form, got, for the main verb; use of gets is ungrammatical).

Ancient Greek verbs have four moods (indicative, imperative, subjunctive and optative), three voices (active, middle and passive), as well as three persons (first, second and third) and three numbers (singular, dual and plural).

• In the indicative mood there are seven tenses: present, imperfect, future, aorist (the equivalent of past simple), perfect, pluperfect, and future perfect. (The last two, especially the future perfect, are rarely used).
• In the subjunctive and imperative mood, however, there are only three tenses (present, aorist, and perfect).
• The optative mood, infinitives and participles are found in four tenses (present, aorist, perfect, and future) and all three voices.

The distinction of the "tenses" in moods other than the indicative is predominantly one of aspect rather than time.

In linguistics and rhetoric, the historical present or historic present, also called dramatic present or narrative present, is the employment of the present tense instead of past tenses when narrating past events. It is also often called the "literary present tense". It is typically thought to heighten the dramatic force of the narrative by describing events as if they were still unfolding, and/or by foregrounding some events relative to others.

Relative tense and absolute tense are distinct possible uses of the grammatical category of tense. Absolute tense means the grammatical expression of time reference (usually past, present or future) relative to "now" – the moment of speaking. In the case of relative tense, the time reference is construed relative to a different point in time, the moment being considered in the context. In other words, the reference point (or center of deixis) is the moment of discourse or narration in the case of absolute tense, or a different moment in the case of relative tense.

A further distinction has also been made between "strict relative" tense, which merely expresses time relative to the reference point, and "absolute-relative tense" (such as pluperfect), which expresses time relative to the reference point while also placing the reference point in time relative to the present moment.
