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 word is derived from Late Latin [modus] infinitivus, a derivative of infinitus meaning "unlimited".
In terms of linguistics and grammar, conjugation has two basic meanings. One meaning is the creation of derived forms of a verb from basic forms, or principal parts. It may be affected by person, number, gender, tense, mood, aspect, voice, or other language-specific factors.
A split infinitive is a grammatical construction in which an adverb or adverbial phrase separates the "to" and "infinitive" constituents of what was traditionally called the full infinitive, but is more commonly known in modern linguistics as the to-infinitive. In the history of English language aesthetics, the split infinitive was often deprecated, despite its prevalence in colloquial speech. The opening sequence of the Star Trek television series contains a well-known example, "to boldly go where no man has gone before", wherein the adverb boldly was said to split the full infinitive, to go. Multiple words may split a to-infinitive, such as: "The population is expected to more than double in the next ten years."
English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.
In language, a clause is a constituent that comprises a semantic predicand and a semantic predicate. A typical clause consists of a subject and a syntactic predicate, the latter typically a verb phrase composed of a verb with any objects and other modifiers. However, the subject is sometimes unvoiced if it is retrievable from context, especially in null-subject language but also in other languages, including English instances of the imperative mood.
A gerund is any of various nonfinite verb forms in various languages; most often, but not exclusively, one that functions as a noun. In English, it has the properties of both verb and noun, such as being modifiable by an adverb and being able to take a direct object. The term "-ing form" is often used in English to refer to the gerund specifically. Traditional grammar makes a distinction within -ing forms between present participles and gerunds, a distinction that is not observed in such modern grammars as A Comprehensive Grammar of the English Language and The Cambridge Grammar of the English Language.
In linguistics, a participle is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, participle has been defined as "a word derived from a verb and used as an adjective, as in a laughing face".
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.
The going-to future is a grammatical construction used in English to refer to various types of future occurrences. It is made using appropriate forms of the expression to be going to. It is an alternative to other ways of referring to the future in English, such as the future construction formed with will – in some contexts the different constructions are interchangeable, while in others they carry somewhat different implications.
In grammar, a supine is a form of verbal noun used in some languages. The term is most often used for Latin, where it is one of the four principal parts of a verb. The word refers to a position of lying on one's back, but there exists no widely accepted etymology that explains why or how the term came to be used to also describe this form of a verb.
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 English modal verbs are a subset of the English auxiliary verbs used mostly to express modality. They can be distinguished from other verbs by their defectiveness and by their neutralization.
A modal verb is a type of verb that contextually indicates a modality such as a likelihood, ability, permission, request, capacity, suggestion, order, obligation, or advice. Modal verbs always 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, and must.
The passive voice in English is a grammatical voice whose syntax is marked by a subject followed by a stative verb complemented by a past participle. For example:
A nonfinite verb is a derivative form of a verb unlike finite verbs. Accordingly, nonfinite verb forms are inflected for neither number nor person, and they cannot perform action as the root of an independent clause. In English, nonfinite verbs includee infinitives, participles and gerunds. Nonfinite verb forms in some other languages include converbs, gerundives and supines.
In linguistics, a non-finite clause is a dependent or embedded clause that represents a state or event in the same way no matter whether it takes place before, during, or after text production. In this sense, a non-finite dependent clause represents one process as a circumstance for another without specifying the time when it takes place as in the following examples:
Ancient Greek grammar is morphologically complex and preserves several features of Proto-Indo-European morphology. Nouns, adjectives, pronouns, articles, numerals and especially verbs are all highly inflected.
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.
This article describes the uses of various verb forms in modern standard English language. This includes:
This article describes the syntax of clauses in the English language, chiefly in Modern English. A clause is often said to be the smallest grammatical unit that can express a complete proposition. But this semantic idea of a clause leaves out much of English clause syntax. For example, clauses can be questions, but questions are not propositions. A syntactic description of an English clause is that it is a subject and a verb. But this too fails, as a clause need not have a subject, as with the imperative, and, in many theories, an English clause may be verbless. The idea of what qualifies varies between theories and has changed over time.
