In grammar, a preparatory subject or anticipatory subject [1] [2] is a subject which represents a verb clause later in the sentence. It as a preparatory subject is "commonly used in speech and writing, especially when the subject is longer than the complement and is better placed at the end of the sentence". [3]
is equivalent to
"It" in the first sentence is a preparatory subject, referring to the clause "to play the piano". [4]

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.
In syntax and grammar, a phrase is a group of words which act together as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent.
English grammar is the way in which meanings are encoded into wordings in the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.
In language, a clause is a constituent that links a semantic predicand and a semantic predicate. A typical clause consists of a subject and a syntactic predicate, the latter typically a verb phrase, a verb with any objects and other modifiers. However, the subject is sometimes not said or explicit, often the case in null-subject languages if the subject is retrievable from context, but it sometimes also occurs in other languages such as English(as in imperative sentences and non-finite clauses).
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.
The pronoun who, in English, is an interrogative pronoun and a relative pronoun, used primarily to refer to persons.
The subject in a simple English sentence such as John runs, John is a teacher, or John was run over by a car, is the person or thing about whom the statement is made, in this case John. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees. If there is no verb, as in John - what an idiot!, or if the verb has a different subject, as in John - I can't stand him!, then 'John' is not considered to be the grammatical subject, but can be described as the topic of the sentence.
In linguistics, the topic, or theme, of a sentence is what is being talked about, and the comment is what is being said about the topic. This division into old vs. new content is called information structure. It is generally agreed that clauses are divided into topic vs. comment, but in certain cases the boundary between them depends on which specific grammatical theory is being used to analyze the sentence.
Traditionally, a finite verb is the form "to which number and person appertain", in other words, those inflected for number and person. Verbs were originally said to be finite if their form limited the possible person and number of the subject.
In syntax, verb-second (V2) word order places the finite verb of a clause or sentence in second position with a single constituent preceding it, which functions as the clause topic.
In linguistics and grammar, a sentence is a linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog." In traditional grammar, it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a subject and predicate. In non-functional linguistics it is typically defined as a maximal unit of syntactic structure such as a constituent. In functional linguistics, it is defined as a unit of written texts delimited by graphological features such as upper case letters and markers such as periods, question marks, and exclamation marks. This notion contrasts with a curve, which is delimited by phonologic features such as pitch and loudness and markers such as pauses; and with a clause, which is a sequence of words that represents some process going on throughout time.
A subordinate clause, dependent clause or embedded clause is a clause that is embedded within a complex sentence. For instance, in the English sentence "I know that Bette is a dolphin", the clause "that Bette is a dolphin" occurs as the complement of the verb "know" rather than as a freestanding sentence. Subtypes of dependent clauses include content clauses, relative clauses, and adverbial clauses.
In grammar, a complement is a word, phrase, or clause that is necessary to complete the meaning of a given expression. Complements are often also arguments.
The term predicate is used in one of two ways in linguistics and its subfields. The first defines a predicate as everything in a standard declarative sentence except the subject, and the other views it as just the main content verb or associated predicative expression of a clause. Thus, by the first definition the predicate of the sentence Frank likes cake is likes cake. By the second definition, the predicate of the same sentence is just the content verb likes, whereby Frank and cake are the arguments of this predicate. Differences between these two definitions can lead to confusion.
The passive voice in English is a grammatical "voice". The noun or noun phrase that would be the object of a corresponding active sentence appears as the subject of a sentence or clause in the passive voice.
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:
In linguistics, an argument is an expression that helps complete the meaning of a predicate, the latter referring in this context to a main verb and its auxiliaries. In this regard, the complement is a closely related concept. Most predicates take one, two, or three arguments. A predicate and its arguments form a predicate-argument structure. The discussion of predicates and arguments is associated most with (content) verbs and noun phrases (NPs), although other syntactic categories can also be construed as predicates and as arguments. Arguments must be distinguished from adjuncts. While a predicate needs its arguments to complete its meaning, the adjuncts that appear with a predicate are optional; they are not necessary to complete the meaning of the predicate. Most theories of syntax and semantics acknowledge arguments and adjuncts, although the terminology varies, and the distinction is generally believed to exist in all languages. Dependency grammars sometimes call arguments actants, following Lucien Tesnière (1959).
Subject–auxiliary inversion is a frequently occurring type of inversion in English, whereby a finite auxiliary verb – taken here to include finite forms of the copula be – appears to "invert" with the subject. The word order is therefore Aux-S (auxiliary–subject), which is the opposite of the canonical SV (subject–verb) order of declarative clauses in English. The most frequent use of subject–auxiliary inversion in English is in the formation of questions, although it also has other uses, including the formation of condition clauses, and in the syntax of sentences beginning with negative expressions.
A predicative expression is part of a clause predicate, and is an expression that typically follows a copula, e.g. be, seem, appear, or that appears as a second complement of a certain type of verb, e.g. call, make, name, etc. The most frequently acknowledged types of predicative expressions are predicative adjectives and predicative nominals. The main trait of all predicative expressions is that they serve to express a property that is assigned to a "subject", whereby this subject is usually the clause subject, but at times it can be the clause object. A primary distinction is drawn between predicative and attributive expressions. Further, predicative expressions are typically not clause arguments, and they are also typically not clause adjuncts. There is hence a three-way distinction between predicative expressions, arguments, and adjuncts.
In grammar, sentence and clause structure, commonly known as sentence composition, is the classification of sentences based on the number and kind of clauses in their syntactic structure. Such division is an element of traditional grammar.
