Sentence elements are the groups of words that combine together to comprise the ‘building units’ of a well-formed sentence. A sentence element approach to grammar assumes a top-down methodology. In other words, it starts with the sentence as a whole and then divides it into its functional components.

There are five types of sentence element: 1 subject 2 verb 3 object 4 predicative (aka complement) 5 adverbial See subject (grammar) for the linguistic definition of subject. ... A verb is a part of speech that usually denotes action (bring, read), occurrence (decompose, glitter), or a state of being (exist, stand). Depending on the language, a verb may vary in form according to many factors, possibly including its tense, aspect, mood and voice. ... WordNet gives four main senses for the English noun object: a physical entity; something that is within the grasp of the senses; an aim, target or objective — see Object (task); a grammatical Object — either a direct object or an indirect object the focus of cognitions or feelings. ... In mathematics, a predicate is a relation. ... The word complement (with an e in the second syllable, not to be confused with a different word, compliment with an i) has a number of uses. ... In linguistics, an adverbial is a sentence function like subject and object and so on. ...

In the sentence below every type of sentence element is present and is represented in this example by a single word.

• They elected him president yesterday.

They (=subject), elected (=verb), him (=object), president (=predicative), yesterday (=adverbial)

The subject and predicate

All the sentence elements except the subject fall into the predicate of the sentence. The subject is the topic of the sentence and the predicate is the comment on the subject. Look at the example below. In mathematics, a predicate is a relation. ... Topic can refer to: The topic or theme of a proposition in linguistics An XML topic (a kind of resource) This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ... Look up Comment on Wiktionary, the free dictionary In computer programming, comments are parts of the source code which, together with its layout, are used to explain the code. ...

• Mr Jenner ate cabbage in the garden.

In this example Mr Jenner is the subject, and ate cabbage in the garden is the predicate. Mr Jenner is the topic; and the comment is that he ate cabbage in the garden.

The subject is necessarily a nominal (noun, pronoun, noun phrase or clause). Wikipedia does not yet have an article with this exact name. ... A noun, or noun substantive, is a part of speech (a word or phrase) which can co-occur with (in)definite articles and attributive adjectives, and function as the head of a noun phrase. ... In linguistics and grammar, a pronoun is a pro-form that substitutes for a noun phrase. ... In linguistics, a noun phrase is a phrase whose Head is a noun. ... In grammar, a clause is a group of words consisting of a subject and a predicate, although, in non-finite clauses, the subject is often not explicitly given. ...

The verb governs the predicate and determines whether objects, predicatives and adverbials are required, permitted or proscribed. Look at the example below:

• My older brother gave Lorna a book yesterday in the garden.

In this example the verb to give requires two objects (direct: a book, indirect Lorna) and permits temporal and locative adverbials (yesterday and in the garden respectively)

Sentence elements comprising the predicate

These elements are the verb phrase, objects, predicatives and adverbials.

verb group

Every verb group has a main verb, which may stand alone or may be preceded by auxiliary verbs which determine the mood, tense, voice or aspect of the main verb. The main verbs determines which other sentence elements are required or permitted in the predicate, (selection restriction). Mood may refer to: chese Grammatical mood Emotional mood This is a disambiguation page, a list of pages that otherwise might share the same title. ... Grammatical tense is a way languages express the time at which an event described by a sentence occurs. ... The word voice can be used to refer to: Sound: The human voice. ... Aspect can refer to: Aspect (computer science) is a feature that is linked to many parts of a program, but which is not necessarily the primary function of the program. ...

Main verbs may be classified:

copular verb: this links a subject to predicative.

• Miss Gold seems happy (SUBJECT + COPULA VERB + PREDICATIVE)

stative verb: this establishes a state not an action.

• We lay in our beds. (SUBJECT + STATIVE VERB + ADVERBIAL)

active verb: the sentence describes an action (i.e. a change of state).

• Mr Jenner left the room. (SUBJECT + ACTIVE VERB + DIRECT OBJECT)

objects

An object is an entity involved in the subject's ‘performance’ of the verb. Look at this sentence below:

• Mr Bibby kicked the ball. (object)

• Mr Bibby is the subject (the doer or performer), kick is the verb (the action) and the ball is object involved in the action.

The main verb in the sentence determines whether there can or must be objects in the sentence, and, if so, how many and of what type. If the verb is transitive, as is the verb to kick in the example above, the action is ‘carried over’ and an object is required. If the verb is intransitive there is no objects. Look at the examples below.

• The train arrived. (verb to arrive cannot take an object. It is intransitive)

• Mr Jenner enjoyed the film. (verb to enjoy is monotransitive, and requires one object)

• Miss Gold eats a banana every morning. (verb to eat is ambitranistive and permits an object)

• John gave Mary the book. (verb to give permits two objects; it is ditransitive)

There are three types of object:

• We threw stones. (direct object)

• We listened to the radio. (prepositional object)

• They advised him to open a shop. (non-prepositional indirect object)

Objects are either nominals (nouns, pronouns, noun phrases or clauses) or else prepositional phrases which consist of a preposition followed by a nominal.

predicatives (AKA subject and object complements)

Predicatives are nominals or adjectivals which tell us more about the subject or object by means of the verb.

In the following examples the predicative is telling us more about the subject. Subject predicatives are necessary sentence elements, i.e. if they are removed a well-formed sentence does NOT remain.

• The bag seems heavy. (adjectival)

• That man is a thief. (nominal)

In the following examples the predicative is telling us more about the object. Object predicatives are non-obligatory sentence elements, i.e. if they are removed a well-formed sentence does remains.

• We painted the house yellow. (adjectival)

• They elected him president. (nominal)

adverbials

The subject, verb phrase, objects and predicatives form the core of a sentence. Any other element is adverbial; it concerns the circumstances of the sentence (when, where) or relates the sentence to something else. There are four adverbials in the sentence below.

• Lorna arrived (1)here (2)yesterday (3)by car (4)despite the rain.

Adverbials may always be added to a sentence, but some main verbs require adverbials for a well formed-sentence, as in the following example:

• Lorna put the book onto the table.

As sentence elements, there are three main types of adverbials:

adverbial adjunct – integral to sentence meaning and can be removed leaving a well-formed sentence.

• Mr Bibby saw her yesterday.

obligatory adverbial – integral to sentence meaning but cannot be removed.

• They treated her well.

adverbial disjunct - linking the sentence to another, and is removable.

• I, however, thought otherwise.

Internal structure of sentence elements

Sentence elements may be one of three forms: a (single) word, a phrase, a clause. A word is a unit of language that carries meaning and consists of one or more morphemes which are linked more or less tightly together. ... A phrase is a group of words that functions as a single unit in the syntax of a sentence. ... In grammar, a clause is a group of words consisting of a subject and a predicate, although, in non-finite clauses, the subject is often not explicitly given. ...

single word sentence elements

Single word sentence elements may be directly related to parts of speech. A single word subject or object is necessarily a noun. A single word verb is a verb. A single word predicative is either a noun or an adjective. Single word adverbials are adverbs.

phrasal sentence elements

A phrasal sentence element is any group of words which collectively serve as a sentence element, but which does NOT constitute a clause.

We can identify four types of phrase.

noun: these phrases have a noun (or pronoun) head. Adjectives, determiners and relative clauses may modify the noun. Noun phrases may form the subject, object, predicative and adverbial sentence elements.

• the old man who lived next door (with pre and post modification)

prepositional: these phrases have the structure of a preposition followed by a noun phrase. Prepositional phrases may form prepositional objects and adverbials.

• Lorna gave the book to the old man. (SUBJECT + VERB + OBJECT + PREP OBJECT)
• We saw them in the evening. (SUBJECT + VERB + OBJECT + ADVERBIAL)

adjectival: these phrases consist of an adjective and possible modifiers. As sentence elements adjectival phrases are predicatives.

• She was very able to write a book. (with pre and post modification)

verbal: the verbal group consists of a main verb, possible auxiliary verbs and possible adverbial particles. They only occur the verbal structure of the sentence.

• We will have washed up. (SUBJECT + VERBAL STRUCTURE)

clausal sentence elements

• We left after his friend had arrived. (the adverbial adjunct is a clause)
