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:
In the sentence below every type of sentence element is present and is represented in this example by a single word.
They (=subject), elected (=verb), him (=object), president (=predicative), yesterday (=adverbial)
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).
The verb governs the predicate and determines whether objects, predicatives and adverbials are required, permitted or proscribed. Look at the example below:
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)
Main verbs may be classified:
copular verb: this links a subject to predicative.
stative verb: this establishes a state not an action.
active verb: the sentence describes an action (i.e. a change of state).
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.
There are three types of object:
Objects are either nominals (nouns, pronouns, noun phrases or clauses) or else prepositional phrases which consist of a preposition followed by a nominal.
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.
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 remain.
Adverbials may always be added to a sentence, but some main verbs require adverbials for a well formed-sentence, as in the following example:
As sentence elements, there are four main types of adverbials:
adverbial adjunct – integral to sentence meaning and can be removed leaving a well-formed sentence.
obligatory adverbial – integral to sentence meaning but cannot be removed.
adverbial conjunct - linking the sentence to another, and is removable.
adverbial disjunct - making a comment on the sentence
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.
prepositional: these phrases have the structure of a preposition followed by a noun phrase. Prepositional phrases may form prepositional objects and adverbials.
adjectival: these phrases consist of an adjective and possible modifiers. As sentence elements adjectival phrases are predicatives.
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.
The clause can function as a subject, object and adverbial sentence element.
Clauses, whether they are sentence elements or not, are themselves composed of sentence elements. Look at the example below.
