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".
English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.
An auxiliary verb is a verb that adds functional or grammatical meaning to the clause in which it occurs, so as to express tense, aspect, modality, voice, emphasis, etc. Auxiliary verbs usually accompany an infinitive verb or a participle, which respectively provide the main semantic content of the clause. An example is the verb have in the sentence I have finished my lunch. Here, the auxiliary have helps to express the perfect aspect along with the participle, finished. Some sentences contain a chain of two or more auxiliary verbs. Auxiliary verbs are also called helping verbs, helper verbs, or (verbal) auxiliaries. Research has been conducted into split inflection in auxiliary verbs.
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.
In linguistics, a defective verb is a verb that either lacks a conjugated form or entails incomplete conjugation, and thus cannot be conjugated for certain grammatical tenses, aspects, persons, genders, or moods that the majority of verbs or a "normal" or regular verb in a particular language can be conjugated for. That is to say, a defective verb lacks forms that most verbs in a particular language have.
Verbs constitute one of the main parts of speech 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.
Shall and will are two of the English modal verbs. They have various uses, including the expression of propositions about the future, in what is usually referred to as the future tense of English.
A tag question is a construction in which an interrogative element is added to a declarative or an imperative clause. The resulting speech act comprises an assertion paired with a request for confirmation. For instance, the English tag question "You're John, aren't you?" consists of the declarative clause "You're John" and the interrogative tag "aren't you?"
Englishauxiliary verbs are a small set of English verbs, which include the English modal auxiliary verbs and a few others. Although the auxiliary verbs of English are widely believed to lack inherent semantic meaning and instead to modify the meaning of the verbs they accompany, they are nowadays classed by linguists as auxiliary on the basis not of semantic but of grammatical properties: among these, that they invert with their subjects in interrogative main clauses and are negated either by the simple addition of not or by negative inflection.
A modal verb is a type of verb that contextually indicates a modality such as a likelihood, ability, permission, request, capacity, suggestion, order, obligation, necessity, possibility or advice. Modal verbs generally accompany the base (infinitive) form of another verb having semantic content. In English, the modal verbs commonly used are can, could, may, might, shall, should, will, would, ought to, used to and dare.

The pluperfect, usually called past perfect in English, is a type of verb form, generally treated as a grammatical tense in certain languages, relating to an action that occurred prior to an aforementioned time in the past. Examples in English are: "we had arrived"; "they had written".
The English language has many irregular verbs, approaching 200 in normal use—and significantly more if prefixed forms are counted. In most cases, the irregularity concerns the past tense or the past participle.
While the English language lacks distinct inflections for mood, an English subjunctive is recognized in most grammars. Definition and scope of the concept vary widely across the literature, but it is generally associated with the description of something other than apparent reality. Traditionally, the term is applied loosely to cases in which one might expect a subjunctive form in related languages, especially Old English and Latin. This includes conditional clauses, wishes, and reported speech. Modern descriptive grammars limit the term to cases in which some grammatical marking can be observed, nevertheless coming to varying definitions.
Verbs in Middle High German are divided into strong or weak verbs. Strong verbs indicate tense by a change in the quality of a vowel, while weak verbs indicate tense by the addition of an ending.
Do-support, in English grammar, is the use of the auxiliary verb do, including its inflected forms does and did, to form negated clauses and questions as well as other constructions in which subject–auxiliary inversion is required.
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 describes the uses of various verb forms in modern standard English language. This includes:
Prototypical conditional sentences in English are those of the form "If X, then Y". The clause X is referred to as the antecedent, while the clause Y is called the consequent. A conditional is understood as expressing its consequent under the temporary hypothetical assumption of its antecedent.
In linguistics and grammar, affirmation and negation are ways in which grammar encodes positive and negative polarity into verb phrases, clauses, or other utterances. An affirmative (positive) form is used to express the validity or truth of a basic assertion, while a negative form expresses its falsity. For example, the affirmative sentence "Joe is here" asserts that it is true that Joe is currently located near the speaker. Conversely, the negative sentence "Joe is not here" asserts that it is not true that Joe is currently located near the speaker.
