Subjects, predicates, objects, complements and adverbials.
A sentence is built from grammatical elements such as subjects, predicates, objects, complements, and adverbials.
Understanding these elements helps learners identify sentence structure and understand how different words and phrases function within a clause.
The subject is the person, thing, or concept that a clause is about or that performs or experiences the action expressed by the verb.
For example, The children are playing and The weather changed suddenly.
A subject can be a single word or a longer noun phrase containing determiners, adjectives, and other modifiers.
For example, Children laughed and The children from the neighbouring school laughed.
The predicate is the part of the clause that contains the verb and provides information about the subject.
For example, in The children are playing outside, are playing outside forms the predicate.
A finite verb carries tense or agrees with the subject and forms the grammatical core of a finite clause.
For example, works, worked, is working, and has finished are finite verb forms.
An object is a noun phrase or other constituent that is directly affected by or associated with the action of certain verbs.
For example, She opened the door and They bought a new car.
A direct object is the primary object of a transitive verb and commonly answers the question of what or whom after the verb.
For example, She read the book and We invited John.
An indirect object identifies the recipient or beneficiary of an action involving another object.
For example, She gave me a present. Me is the indirect object and a present is the direct object.
Some verbs can take two objects in a construction where one object is the recipient and the other is the thing transferred.
For example, They sent me an email and She bought her son a bicycle.
An object complement identifies, describes, or changes the status of the direct object.
For example, They elected him president and The news made her angry.
A subject complement identifies or describes the subject, commonly after linking verbs such as be, seem, become, and remain.
For example, She is a doctor and The situation became difficult.
A predicative noun is a noun phrase functioning as a subject complement.
For example, John is a teacher and She became the team leader.
A predicative adjective functions as a subject complement and describes the subject after a linking verb.
For example, The room is quiet and The children became excited.
Adverbials provide information about circumstances such as time, place, manner, frequency, reason, or condition.
For example, She works in London, He arrived yesterday, and They spoke quietly.
A time adverbial indicates when or for how long an event occurs.
For example, We arrived yesterday and She has lived here for five years.
A place adverbial indicates where an event occurs or where someone or something is located.
For example, They live in London and The children are playing outside.
A manner adverbial describes how an action is performed.
For example, She spoke quietly and He completed the task carefully.
A frequency adverbial indicates how often an event occurs.
For example, She often works late and They visit us every weekend.
An adverbial can explain why an action occurs or what purpose it serves.
For example, He left because he was tired and She went to the shop to buy milk.
A complement is required or strongly selected by certain words or structures, while an adverbial generally provides additional circumstantial information.
For example, She became a doctor requires a subject complement, while She worked in London adds an optional place adverbial.
A transitive verb normally requires or permits a direct object.
For example, She opened the door and They discussed the problem.
An intransitive verb does not take a direct object.
For example, The baby slept and The guests arrived.
Linking verbs connect the subject to a subject complement rather than expressing a direct action on an object.
Common examples include be, seem, become, appear, remain, and feel.
Different verbs select different complements and sentence patterns.
For example, put normally requires an object and a place expression, while seem can be followed by an adjective or infinitive.
A sentence element can itself be a clause or phrase rather than a single word.
For example, What she said surprised me contains a clause functioning as the subject.
The same basic sentence elements can be arranged differently to emphasize different information.
For example, The manager gave John the report and John was given the report by the manager present the same event from different structural viewpoints.
Some sentence elements are required by the verb or construction, while others can be omitted without making the clause ungrammatical.
For example, She put the keys on the table requires a place complement, while She slept on the sofa contains an optional place expression.
An object complement describes or identifies the object, while a subject complement describes or identifies the subject.
Compare They painted the door red with The door became red.
Sentence analysis requires identifying each element by its grammatical function rather than simply by its position.
A noun phrase can function as a subject, object, or complement, and an adverbial can occur in different positions.
Identify sentence elements according to their grammatical function and the requirements of the verb or construction.
Common mistakes include confusing objects with complements, treating every adverb as an adverbial, assuming every verb takes an object, and identifying elements solely by their position in the sentence.
