Typical for an Indo-European language,
English grammar follows
accusative morphosyntactic alignment. Unlike other Indo-European languages, English has largely abandoned the inflectional
case system in favour of
analytic constructions. Only the
personal pronouns retain morphological case more strongly than any other
word class. English distinguishes at least seven major word classes: verbs, nouns, adjectives, adverbs, determiners (including articles), prepositions, and conjunctions. Some analyses add pronouns as a class separate from nouns, and subdivide conjunctions into
subordinators and
coordinators, and add the class of interjections. English also has a rich set of
auxiliary verbs, such as
have and
do, expressing the categories of mood and aspect. Questions are marked by
do-support,
wh-movement (fronting of question words beginning with
wh-) and word order
inversion with some verbs. Some traits typical of Germanic languages persist in English, such as the distinction between irregularly inflected
strong stems inflected through
ablaut (i.e. changing the vowel of the stem, as in the pairs
speakspoke and
footfeet) and weak stems inflected through affixation (such as
loveloved,
handhands). Vestiges of the case and gender system are found in the pronoun system (
hehim,
whowhom); similarly, traces of more complex verb conjugation are seen in the inflection of the
copula verb
to be. They often agree with the noun in
number. They do not typically inflect for degree of comparison.
Pronouns, case, and person English pronouns conserve many traits of case and gender inflection. The personal pronouns retain a difference between subjective and objective case in most persons (, , , , ) as well as an animateness distinction in the third person singular (distinguishing
it from the three sets of animate third person singular pronouns) and an optional gender distinction in the animate third person singular (distinguishing between feminine ,
epicene , and masculine . The
subjective case corresponds to the Old English
nominative case, and the
objective case is used in the sense both of the previous
accusative case (for a patient, or direct object of a transitive verb), and of the Old English dative case (for a recipient or
indirect object of a transitive verb). The subjective is used when the pronoun is the subject of a finite clause, otherwise the objective is used. While grammarians such as
Henry Sweet and
Otto Jespersen noted that the English cases did not correspond to the traditional Latin-based system, some contemporary grammars, including
The Cambridge Grammar of the English Language, retain traditional
nominative and
accusative labels for the cases. Possessive pronouns exist in dependent and independent forms; the dependent form functions as a determiner specifying a noun (as in
my chair), while the independent form can stand alone as if it were a noun (e.g. "the chair is mine"). Grammatical person in English no longer distinguishes between formal and informal pronouns of address, with the second person singular familiar pronoun
thou that previously existed in the language having fallen almost entirely out of use by the 18th century. Both the second and third persons share pronouns between the plural and singular: • Plural and singular are always identical (
you,
your,
yours) in the second person (except in the reflexive form: ) in most dialects. Some dialects have introduced innovative second person plural pronouns, such as ''y'all
(found in Southern American English and African-American Vernacular English), youse
(found in Australian English), or ye'' (in
Hiberno-English). • In the third person, the series of pronouns (
they,
them,
their,
theirs,
themselves) are used in both plural and singular, and are the only pronouns available for the plural. In the singular, the series (sometimes with the addition of the singular-specific reflexive form
themself) serve as a
gender-neutral set of pronouns. These pronouns are becoming more accepted, especially as part of
LGBTQ culture. Pronouns are used to refer to entities
deictically or
anaphorically. A deictic pronoun points to some person or object by identifying it relative to the speech situationfor example, the pronoun
I identifies the speaker, and the pronoun
you, the addressee. Anaphoric pronouns such as
that refer back to an entity already mentioned or assumed by the speaker to be known by the audience, for example in the sentence "I already told you that". The reflexive pronouns are used when the oblique argument is identical to the subject of a phrase (e.g. "he sent it to himself" or "she braced herself for impact").
Prepositions Prepositional phrases (PP) are phrases composed of a preposition and one or more nouns, e.g. "with the dog", "for my friend", "to school", "in England".
English prepositions have a wide range of usesincluding describing movement, place, and other relations between entities, as well as functions that are syntactic in nature, like introducing complement clauses and oblique arguments of verbs. For example, in the phrase "I gave it to him", the preposition
to marks the indirect object of the verb
to give. Traditionally words were only considered prepositions if they governed the case of the noun they preceded, for example causing the pronouns to use the objective rather than subjective form, "with her", "to me", "for us". But some contemporary grammars no longer consider government of case to be the defining feature of the class of prepositions, rather defining prepositions as words that can function as the heads of prepositional phrases.
Verbs and verb phrases English verbs are inflected for tense and aspect and marked for agreement with a third person present singular subject. Only the copula verb
to be is still inflected for agreement with the plural and first and second person subjects. Auxiliary verbs such as
have and
be are paired with verbs in the
infinitive, past, or progressive forms. They form
complex tenses, aspects, and moods. Auxiliary verbs differ from other verbs in that they can be followed by the negation, and in that they can occur as the first constituent in a question sentence. Most verbs have six inflectional forms. The primary forms are a plain present, a third person singular present, and a preterite (past) form. The secondary forms are a plain form used for the infinitive, a gerund-participle and a past participle. The verb
to bewhich among other uses in English functions as the primary auxiliary verb indicating the
imperfective aspect (e.g. "I
am going"), as well as the
copulais the only verb to retain some of its original conjugation, and takes different inflectional forms depending on the subject. The first person present form is
am, the third person singular form is
is, and the form
are is used in the second person singular and all three plurals. The only verb past participle is
been and its gerund-participle is
being.
Tense, aspect, and mood English has two primary tenses, past (preterite) and non-past. The preterite is inflected by using the preterite form of the verb, which for the regular verbs includes the suffix
-ed, and for the strong verbs either the suffix
-t or a change in the stem vowel. The non-past form is unmarked except in the third person singular, which takes the suffix
-s. English does not have future verb forms. The future tense is expressed periphrastically with one of the auxiliary verbs
will or
shall. Many varieties also use a
near future constructed with the
phrasal verb "be going to" (
going-to future). Further aspectual distinctions are shown by auxiliary verbs, primarily
have and
be, which show the contrast between a perfect and non-perfect past tense ("I have run" vs. "I was running"), and compound tenses such as preterite perfect ("I had been running") and present perfect ("I have been running"). For the expression of mood, English uses a number of modal auxiliaries, such as
can,
may,
will,
shall and the past tense forms
could,
might,
would,
should. There are also
subjunctive and
imperative moods, both based on the plain form of the verb (i.e. without the third person singular
-s), for use in subordinate clauses (e.g. subjunctive: "It is important that he run every day"; imperative
Run!). An infinitive form, that uses the plain form of the verb and the preposition
to, is used for verbal clauses that are syntactically subordinate to a finite verbal clause. Finite verbal clauses are those that are formed around a verb in the present or preterite form. In clauses with auxiliary verbs, they are the finite verbs and the main verb is treated as a subordinate clause. For example, "he has to go" where only the auxiliary verb
have is inflected for time and the main verb
to go is in the infinitive, or in a complement clause such as "I saw him leave", where the main verb is
see, which is in a preterite form, and
leave is in the infinitive.
Phrasal verbs English also makes frequent use of constructions traditionally called
phrasal verbs, verb phrases that are made up of a verb root and a preposition or particle that follows the verb. The phrase then functions as a single predicate. In terms of intonation the preposition is fused to the verb, but in writing it is written as a separate word. Examples of phrasal verbs are "to get up", "to ask out", "to get together", and "to put up with". The phrasal verb frequently has a highly
idiomatic meaning that is more specialised and restricted than what can be simply extrapolated from the combination of verb and preposition complement (e.g.
lay off meaning ''terminate someone's employment''). Some grammarians do not consider this type of construction to form a syntactic constituent and hence refrain from using the term "phrasal verb". Instead, they consider the construction simply to be a verb with a prepositional phrase as its syntactic complement, e.g. "he woke up in the morning" and "he ran up in the mountains" are syntactically equivalent.
Adverbs The function of adverbs is to modify the action or event described by the verb by providing additional information about the manner in which it occurs. The example below demonstrates this double marking in a sentence where both object and subject are represented with a third person singular masculine pronoun:
Indirect objects (IO) of ditransitive verbs can be placed either as the first object in a double object construction (S V IO O), such as "I gave
Jane the book" or in a prepositional phrase, such as "I gave the book
to Jane".
Clause syntax English sentences may be composed of one or more clauses, that may in turn be composed of one or more phrases (e.g. noun phrases, verb phrases, prepositional phrases). A clause is built around a verb and includes its constituents, such as any noun or prepositional phrases. Within a sentence, there is always at least one main clause (or matrix clause) whereas other clauses are subordinate to a main clause. Subordinate clauses may function as arguments of the verb in the main clause. For example, in the phrase "I think (that) you are lying", the main clause is headed by the verb
think, the subject is
I, but the object of the phrase is the subordinate clause "(that) you are lying". The subordinating conjunction
that shows that the clause that follows is a subordinate clause, but it is often omitted.
Relative clauses are clauses that function as a modifier or specifier to some constituent in the main clause: For example, in the sentence "I saw the letter that you received today", the relative clause "that you received today" specifies the meaning of the word
letter, the object of the main clause. Relative clauses can be introduced by the pronouns
who,
whose,
whom, and
which as well as by
that (which can also be omitted). In contrast to many other Germanic languages there are no major differences between word order in main and subordinate clauses.
Auxiliary verb constructions English auxiliary verbs are relied upon for many functions, including the expression of tense, aspect, and mood. Auxiliary verbs form main clauses, and the main verbs function as heads of a subordinate clause of the auxiliary verb. For example, in the sentence "the dog did not find its bone", the clause "find its bone" is the complement of the negated verb
did not.
Subject–auxiliary inversion is used in many constructions, including focus, negation, and interrogative constructions. The verb
do can be used as an auxiliary even in simple declarative sentences, where it usually serves to add emphasis, as in "I did shut the fridge." However, in the negated and inverted clauses referred to above, it is used because the rules of English syntax permit these constructions only when an auxiliary is present. Modern English does not allow the addition of the negating adverb
not to an ordinary
finite lexical verb, as in *"I know not"it can only be added to an auxiliary (or
copular) verb, hence if there is no other auxiliary present when negation is required, the auxiliary
do is used, to produce a form like "I do not (don't) know." The same applies in clauses requiring inversion, including most questionsinversion must involve the subject and an auxiliary verb, so it is not possible to say *"Know you him?"; grammatical rules require "Do you know him?" Negation is done with the adverb
not, which precedes the main verb and follows an auxiliary verb. A contracted form of not -''n't
can be used as an enclitic attaching to auxiliary verbs and to the copula verb to be
. Just as with questions, many negative constructions require the negation to occur with do''-support, thus in Modern English "I don't know him" is the correct answer to the question "Do you know him?", but not *"I know him not", although this construction may be found in older English. Passive constructions also use auxiliary verbs. A passive construction rephrases an active construction in such a way that the object of the active phrase becomes the subject of the passive phrase, and the subject of the active phrase is either omitted or demoted to a role as an oblique argument introduced in a prepositional phrase. They are formed by using the past participle either with the auxiliary verb
to be or
to get, although not all varieties of English allow the use of passives with
get. For example, putting the sentence "she sees him" into the passive becomes "he is seen (by her)", or "he gets seen (by her)".
Questions Both
yes/no questions and
wh-questions in English are mostly formed using
subject–auxiliary inversion ("Am I going tomorrow?", "Where can we eat?"), which may require
do-support ("Do you like her?", "Where did he go?"). In most cases,
interrogative words (or wh
-words)which include
who,
what,
when,
where,
why, and
howappear in a
fronted position. For example, in the question "What did you see?", the word
what appears as the first constituent despite being the
grammatical object of the sentence. When the
wh-word is the subject or forms part of the subject, no inversion occurs (e.g. "Who saw the cat?").
Prepositional phrases can also be fronted when they are the questions theme (e.g. "To whose house did you go last night?"). The personal interrogative pronoun
who is the only interrogative pronoun to still show inflection for case, with the variant
whom serving as the objective case form, although this form may be going out of use in many contexts.
Discourse level syntax While English is a subject-prominent language, at the discourse level it tends to use a
topic–comment structure, where the known information (topic) precedes the new information (comment). Because of the strict SVO syntax, the topic of a sentence generally has to be the grammatical subject of the sentence. In cases where the topic is not the grammatical subject of the sentence, it is often promoted to subject position through syntactic means. One way of doing this is through a passive construction, "the girl was stung by the bee". Another way is through a
cleft sentence where the main clause is demoted to be a complement clause of a copula sentence with a
dummy subject such as
it or
there, e.g. "it was the girl that the bee stung", "there was a girl who was stung by a bee". Dummy subjects are also used in constructions where there is no grammatical subject such as with impersonal verbs (e.g. "it is raining") or in existential clauses ("there are many cars on the street"). Through the use of these complex sentence constructions with informationally vacuous subjects, English is able to maintain both a topic–comment sentence structure and a SVO syntax.
Focus constructions emphasise a particular piece of new or salient information within a sentence, generally through allocating the main sentence level stress on the focal constituent. For example, "the girl was stung by
a bee" (emphasising it was a bee and not, for example, a wasp that stung her), or "
the girl was stung by a bee" (contrasting with another possibility, for example that it was the boy). Topic and focus can also be established through syntactic dislocation, either preposing or postposing the item to be focused on relative to the main clause. For example, "That girl over there, she was stung by a bee", emphasises the girl by preposition, but a similar effect could be achieved by postposition, "she was stung by a bee, that girl over there", where reference to the girl is established as an afterthought.
Cohesion between sentences is achieved through the use of deictic pronouns as
anaphora (e.g. "that is exactly what I mean" where
that refers to some fact known to both interlocutors, or
then used to locate the time of a narrated event relative to the time of a previously narrated event).
Discourse markers such as
oh,
so, or
well, also signal the progression of ideas between sentences and help to create cohesion. Discourse markers are often the first constituents in sentences. Discourse markers are also used for
stance taking in which speakers position themselves in a specific attitude towards what is being said, for example, "no way is that true!" (the idiomatic marker "no way!" expressing disbelief), or "boy! I'm hungry" (the marker
boy expressing emphasis). While discourse markers are particularly characteristic of informal and spoken registers of English, they are also used in written and formal registers. == Vocabulary ==
