Complement (linguistics)

In grammar, a complement is a word, phrase or clause that is necessary to complete the meaning of a given expression.[1][2] Complements are often also arguments (i.e., expressions that help complete the meaning of a predicate). There are indicative as well as non-indicative complements in languages. Non-indicative complements follow the appropriate complementizers. Indicative complements do not follow complementizers, but instead are included with special markers and clauses.[3]

Predicative, subject and object complements

In many non-theoretical grammars, the terms subject complement and object comp are employed to denote the predicative expressions (e.g. predicative adjectives and nominals) that serve to assign a property to a subject or object,[4] e.g.

Ryan is upset. – Predicative adjective as subject complement
Rachelle is the boss. – Predicative nominal as subject complement
That made Michael lazy. – Predicative adjective as object complement
We call Rachelle the boss. – Predicative nominal as object complement

This terminology is used in grammar books. For example:[5]

Type Verb Example Elements
SV intransitive The sun is shining. subject, verb
SVO monotransitive That lecture bored me. subject, verb, object
SVC copular Your dinner seems ready. subject, verb, subject complement
SVA copular My office is in the next building. subject, verb, adverbial
SVOO ditransitive I must send my parents an anniversary card. subject, verb, indirect object, direct object
SVOC complex-transitive Most students have found her reasonably helpful. subject, verb, object, object complement
SVOA complex-transitive You can put the dish on the table. subject, verb, object, adverbial

However, this use of terminology is avoided by many modern theories of syntax, which typically view the expressions in bold as part of the clause predicate, which means they are not complements of the subject or object, but rather they are properties that are predicated of the subject or object.

The Cambridge Grammar of the English Language[6] assigns the term "predicate complement" to both uses, and shifts the terminological distinction to the verb:

Ed seemed quite competent: — complex-intransitive verb + predicative complement
She considered Ed quite competent : — complex-transitive verb + predicative complement [7]

Complements as arguments

In many modern grammars (for instance in those that build on the X-bar framework), the object argument of a verbal predicate is called a complement. In fact, this use of the term is the one that currently dominates in linguistics. A main aspect of this understanding of complements is that the subject is usually NOT a complement of the predicate,[8] e.g.

He wiped the counter. – the counter is the object complement of the verb wiped.
She scoured the tub. – the tub is the object complement of the verb scoured.

The noun phrases (NPs) the counter and the tub are necessary to complete the meaning of the verbs wiped and scoured, respectively; hence they are complements

While it is less common to do so, one sometimes extends this reasoning to subject arguments:[9]

He wiped the counter. – He is the subject complement of the verb wiped.
She scoured the tub. – She is the subject complement of the verb scoured.

In these examples, the subject and object arguments are taken to be complements. In this area, then, the terms complement and argument overlap in meaning and use. Note that this practice takes a subject complement to be something very different from the subject complements of traditional grammar, which are predicative expressions, as just mentioned above.

Complements broadly construed

Construed in the broadest sense, any time a given expression is somehow necessary in order to render another expression "complete", it can be characterized as a complement of that expression, e.g.[10]

with the class – The NP the class is the complement of the preposition with.
Jim will help. – The main verb help is the complement of the auxiliary verb will.
Chris gave up. – The particle up is the complement of the verb gave.
as a friend – The NP a friend is the complement of the particle of comparison as.

Construed in this broad sense, many complements cannot be understood as arguments. The argument concept is tied to the predicate concept in a way that the complement concept is not.

In linguistics, an adjunct is an optional, or structurally dispensable, part of a sentence, clause, or phrase that, when removed, will not affect the remainder of the sentence except to discard from it some auxiliary information.[1] A more detailed definition of the adjunct emphasizes its attribute as a modifying form, word, or phrase that depends on another form, word, or phrase, being an element of clause structure with adverbial function.[2] An adjunct is not an argument (nor is it a predicative expression), and an argument is not an adjunct. The argument-adjunct distinction is central in most theories of syntax and semantics. The terminology used to denote arguments and adjuncts can vary depending on the theory at hand. Some dependency grammars, for instance, employ the term circonstant (instead of adjunct), following Tesnière (1959).

Tokelauan Language Complements

The Tokelauan language makes use of complementizers pe, ke, oi, and ona. The complementizer pe is used for indicative complements, while ke, oi, and ona are used for non-indicative complements.

Pe: Complement used in sentences pertaining to knowledge.

Example: Ko taku fakatatau lava pe na maua lava te vaiaho.

TOP 1sg.POSSguess INT COMPT/A obtain INT DET week

'My guess was that a full week had passed.'[3]

Ke: Complement used in sentences pertaining to purpose.

Example: Kua fiu foki ke-iru-au a!

T/A fed-up indeed COMP drink 1sg EXCLM

‘[They] were tired of trying to get me to drink.'[3]

Ona: Complement used in sentences pertaining to “phasal, modal, and commentative predicates.”

Example: Kua tatau ono fai he fale.

T/A necessary COMP make a house

'It had become necessary to acquire a house'[3]

Oi: Complement used in sentences pertaining to items of sequence.

Example: Kuo toeitiiti ol nofo mti te fet0 tEia.

T/A be-soon COMP sit DIR DET star DEM

'Very soon that star will be in the ascendant.'[3]

The Tokelauan language also must take into mind the systematics of its complements. There is a bonding hierarchy between the complements and its sentences. According to Hooper’s research, there are four elements that in Tokelauan semantics that determine the strength of the bond between the complement and rest of the sentence. In the binding system, the complements act inversely to the verb of the sentence. Therefore, if the strength of the verb is higher on the binding scale, the complement is unlikely to appear as its own separate clause. The four elements are: Subject/agent case marking, Verb modalities, Fusion or co-lexicalization, and Separation.[3]

Subject/agent case marking: “‘The higher the main verb is on the binding scale, the less likely is the subject/agent of the complement to display the case-marking characteristics of subjects/agents of main clauses.’”[3] (Quoted from Givón)

Verb modalities: “‘The higher the main verb is on the binding scale, the less likely is the complement verb to display the tense-aspect-modality markings characteristics of main-clause verbs.’”[3] (Quoted from Givón)

Fusion or co-lexicalization: “‘The higher the main verb is on the binding scale, the more likely is the complement verb to co-lexicalize with the main verb.’”[3] (Quoted from Givón)

Separation: “‘The higher the main verb is on the binding scale, the less likely it is that a subordinating morpheme would separate the complement clause from the main clause.’”[3] (Quoted from Givón)
