In [[grammar]], a '''complement''' is that which '''completes''' a [[sentence]]. For some sentences, Subject + Verb is enough ("John runs"), for others, we instinctively feel that something more is required ("John built" -- we want to ask "what?"). There may be more than one Object, or Complement, in a Clause.

In [[grammar]], a '''complement''' is that which '''completes''' something.  This is most usually used of a [[sentence]]. For some sentences, Subject + [[Verb (structural element)|Verb]] is enough ("John runs"). For others, we instinctively feel that something more is required ("John built" -- we want to ask "what? (did John build?)"). Traditionally, the only functions called Complements were elements which may more precisely be called copular Complements.  Many modern grammarians class the elements traditionally called Objects as forms of Complement.  They talk of the '''Complement Object Direct''' (COd) rather than simply a [[Direct Object]], and '''Complement Object Indirect''' (COi) rather than [[Indirect Object]].  The traditional terms are both quicker to write and clearer to use for all but the deepest students of grammar.
  
Traditionally, the only functions called Complements were the copular or adjectival Complement:
+
The '''copular Complement''' (in other words, the element traditionally called simply a '''Complement''') follows the [[Verb (word class)|verb]] '[[to be]]' (this verb is called the [[copula]]), and similar verbs like 'to become'. There are three forms of this complement.
* The '''copular Complement''' follows the [[verb]] '[[to be]]' (this verb is called the ''copula'') or similar verbs like 'to become'. For example, in the sentence “She is Scottish”, ‘Scottish’ is the Complement of ‘is’; in the sentence “This is '''Hull'''”, ‘Hull’ is the '''complement''' of ‘is’; and ‘Thursday’ is the '''complement''' of ‘is’ in “Today is '''Thursday'''” .  
+
*A '''nominal complement''' takes the form of a [[noun]] or [[noun phrase]]. In "My name is Peter", the Subject is the phrase 'My name'; the [[Verb (structural element)|Verb]] is the copula 'is'; and that which completes the sense is the noun 'Peter'. In "It was Thursday", the Subject is the [[pronoun]] 'It'; the Verb is the [[past tense]] of the copula, 'was'; and the noun 'Thursday' completes the sentence. In "It has been a long time", the Subject is again 'It'; the verb is still the copula, but now in the [[present perfect tense]]; and the Complement is the [[noun phrase]] 'a long time'.
* The '''adjectival Complement''' (.... WRITE ME)
+
*An '''adjectival complement''' takes the form of an [[adjective]]. For example, in the sentence "She is Scottish", 'Scottish' is the Complement of 'is'.  In "The weather was lovely", the Complement is the adjective 'lovely'.
 +
*An '''adverbial complement''' - not surprisingly - takes the form of an [[adverbial]], either an [[adverb]] (a single word), an adverbial phrase (a group of words), or an Adverbial Clause (a group of words containing a verb). "It is <u>here</u>" and "It was <u>yesterday</u>" are examples of the first; "It is <u>on the sofa</u>", and "It will be <u>in a few days</u>" are examples of the second; and "It is <u>where you left it</u>" and "That's <u>how you like it</u>" are examples of the third.
  
Other functions may or may not be called Complements, depending on which grammarian you ask:
+
For other forms of grammatical Complement, see '''[[prepositional complement]]''', and the two forms of the Object: the '''[[Direct Object]]''' and the  '''[[Indirect Object]]'''.
  
* The '''prepositional complement''' is the name given to the [[noun]] or [[noun phrase]] that follows a [[preposition]], such as "in '''town'''", "at '''work'''", or "the pen of '''my aunt'''".

* The '''Direct Object''' (in traditional Grammar called just the '''Object''') completes verbs by identifying what or whom they are 'done to' or performed on. Examples: "they built '''a house'''"; "Parliament passes '''laws'''"; "she made '''a mistake'''"; "I like '''him'''"; "she drives '''a Mercedes'''"; "we thought '''brown''', but we chose '''blue'''"; etc. Verbs that require this are called [[transitive]].

Some verbs seem, at first sight, to have two Objects - she gave '''him '''(1) '''a book''' (2); we wish '''you''' (1)''' a happy birthday '''(2); the mother sang '''her baby '''(1) '''a lullaby '''(2); tell '''me''' (1) '''a story (2)'''; etc.
+
 
+
When we look at these more closely, we can see that the two kinds of Object are different. We don't 'sing a baby' in the same way that we 'sing a song'. All the Objects marked (1) in these examples can be replaced by a Preposition Phrase with '''to''' or '''for '''(she gave a book '''to him'''; we wish a happy birthday '''for you'''; the mother sang a lullaby '''to her baby'''; tell a story '''to me'''). These Objects (1) are called '''Indirect Objects'''. (They are never called just 'Objects'.)  An Indirect Object is rarely used without a Direct Object in the same sentence: we don't 'give him' unless we say <u>what</u> it is that we gave to him (though in spoken English, at least, we can say 'tell me'). (''Note that the two Objects can be in the reverse order, ''(2) (1), ''e.g. ''I am writing it for you'';'' King Lear gave his kingdom to his daughters''. Here the Indirect Object is usually a Preposition Phrase.'')

+
'' Some modern grammarians say that the Complement also includes the two Objects. They call the Complement to a copular verb the Complement (C); they call the Direct Object the Complement (Object Direct) (CO''<sub>''d</sub>''''); and they call the Indirect Object the CO''<sub>''i</sub>''''. It seems easier, as well as more traditional, to use the three terms separately.''
+
 
+
''Some verbs - '''Intransitive verbs''' - do not have Objects. These are verbs such as '''to go''', '''to come''' and most verbs of motion, as well as other verbs. They are verbs which talk of actions that the Subject does, but does not do to anyone or anything. Examples: I''''m going'''; she '''was talking'''; the dog '''barked'''; etc.

(For the commonly confused homophones, see compliment - complement)

In grammar, a complement is that which completes something. This is most usually used of a sentence. For some sentences, Subject + Verb is enough ("John runs"). For others, we instinctively feel that something more is required ("John built" -- we want to ask "what? (did John build?)"). Traditionally, the only functions called Complements were elements which may more precisely be called copular Complements. Many modern grammarians class the elements traditionally called Objects as forms of Complement. They talk of the Complement Object Direct (COd) rather than simply a Direct Object, and Complement Object Indirect (COi) rather than Indirect Object. The traditional terms are both quicker to write and clearer to use for all but the deepest students of grammar.

The copular Complement (in other words, the element traditionally called simply a Complement) follows the verb 'to be' (this verb is called the copula), and similar verbs like 'to become'. There are three forms of this complement.

  • A nominal complement takes the form of a noun or noun phrase. In "My name is Peter", the Subject is the phrase 'My name'; the Verb is the copula 'is'; and that which completes the sense is the noun 'Peter'. In "It was Thursday", the Subject is the pronoun 'It'; the Verb is the past tense of the copula, 'was'; and the noun 'Thursday' completes the sentence. In "It has been a long time", the Subject is again 'It'; the verb is still the copula, but now in the present perfect tense; and the Complement is the noun phrase 'a long time'.
  • An adjectival complement takes the form of an adjective. For example, in the sentence "She is Scottish", 'Scottish' is the Complement of 'is'. In "The weather was lovely", the Complement is the adjective 'lovely'.
  • An adverbial complement - not surprisingly - takes the form of an adverbial, either an adverb (a single word), an adverbial phrase (a group of words), or an Adverbial Clause (a group of words containing a verb). "It is here" and "It was yesterday" are examples of the first; "It is on the sofa", and "It will be in a few days" are examples of the second; and "It is where you left it" and "That's how you like it" are examples of the third.

For other forms of grammatical Complement, see prepositional complement, and the two forms of the Object: the Direct Object and the Indirect Object.
