Part of the conjugation of theSpanish verbcorrer, "to run", the lexeme is "corr-". Red represents the speaker, purple theaddressee (or speaker/hearer) and teal a third person. One person represents the singular number and two, the plural number. Dawn represents the past (specifically thepreterite), noon the present and night the future.
Inlinguistics,conjugation (/ˌkɒndʒʊˈɡeɪʃən/con-juu-GAY-shən[1][2]) is the creation of derived forms of averb from itsprincipal parts byinflection (alteration of form according to rules ofgrammar). For instance, the verbbreak can be conjugated to form the wordsbreak,breaks, andbroke. While English has a relatively simple conjugation, other languages such asFrench andArabic orSpanish are more complex, with each verb having dozens of conjugated forms. Some languages such asGeorgian andBasque (some verbs only) have highly complex conjugation systems with hundreds of possible conjugations for every verb.
The term conjugation is applied only to the inflection of verbs, and not of other parts of speech (inflection ofnouns andadjectives is known asdeclension)[citation needed]. It is also generally restricted to denoting the formation offinite forms of a verb – these may be referred to asconjugated forms, as opposed tonon-finite forms, such as aninfinitive,gerund, orparticiple which respectively comprise their own grammatical categories[citation needed].
Conjugation is also the traditional term for a group of verbs that share a similar conjugation pattern in a particular language (averb class). For example,Latin is said to have four conjugations of verbs. This means that anyregular Latin verb can be conjugated in any person, number, tense, mood, and voice by knowing which of the four conjugation groups it belongs to, and its principal parts. A verb that does not follow all of the standard conjugation patterns of the language is said to be anirregular verb. The system of all conjugated variants of a particular verb or class of verbs is called averb paradigm; this may be presented in the form of aconjugation table.
Verbal agreement, orconcord, is amorpho-syntactic construct in which properties of thesubject and/orobjects of averb are indicated by the verb form. Verbs are then said toagree with their subjects (resp. objects).
ManyEnglish verbs exhibit subject agreement of the following sort: whereasI go,you go,we go,they go are all grammatical in standard English,he go is not (except in thesubjunctive, as "They requested thathe go with them"). Instead, a special form of the verbto go has to be used to producehe goes. On the other handI goes,you goes etc. are not grammatical in standard English. (Things are different in some English dialects that lack agreement.) A few English verbs have no special forms that indicate subject agreement (I may,you may,he may), and the verbto be has an additional formam that can only be used with the pronounI as the subject.
Verbs in writtenFrench exhibit more intensive agreementmorphology than English verbs:je suis (I am),tu es ("you are", singularinformal),elle est (she is),nous sommes (we are),vous êtes ("you are", plural),ils sont (they are). Historically, English used to have a similar verbal paradigm. Some historic verb forms are used byShakespeare as slightly archaic or more formal variants (I do,thou dost,he doth) of the modern forms.
Some languages with verbal agreement can leave certain subjectsimplicit when the subject is fully determined by the verb form. InSpanish, for instance, subject pronouns do not need to be explicitly present, but in French, its close relative, they are obligatory. The Spanish equivalent to the Frenchje suis (I am) can be simplysoy (lit. "am"). The pronounyo (I) in the explicit formyo soy is used only for emphasis or to clear ambiguity in complex texts.
Some languages have a richer agreement system in which verbs agree also with some or all of their objects.Ubykh exhibits verbal agreement for the subject, direct object, indirect object, benefaction and ablative objects (a.w3.s.xe.n.t'u.n,you gave it to him for me).
Basque can show agreement not only for subject, direct object and indirect object but it also can exhibit agreement for the listener as the implicit benefactor:autoa ekarri digute means "they brought us the car" (neuter agreement for the listener), butautoa ekarri ziguten means "they brought us the car" (agreement for feminine singular listener).
Languages with a rich agreement morphology facilitate relatively free word order without leading to increased ambiguity. The canonical word order in Basque issubject–object–verb, but all permutations of subject, verb and object are permitted.
In some languages,[5] predicativeadjectives andcopular complements receive a form of person agreement that is distinct from that used on ordinarypredicative verbs. Although that is a form of conjugation in that it refers back to the person of the subject, it is not "verbal" because it always derives frompronouns that have becomeclitic to the nouns to which they refer.[6] An example of nonverbal person agreement, along with contrasting verbal conjugation, can be found fromBeja[7] (person agreement affixes in bold):
InTurkic, and a fewUralic andAustralian Aboriginal languages, predicative adjectives and copular complements take affixes that are identical to those used on predicative verbs, but theirnegation is different. For example, inTurkish:
koş.u.yor.sun “you are running”
çavuş.sun “you are a sergeant”
Under negation, that becomes (negative affixes in bold):
koş.mu.yor.sun “you are not running”
çavuşdeğil.sin “you are not a sergeant”
Therefore, the person agreement affixes used with predicative adjectives and nominals in Turkic languages are considered to be nonverbal in character. In some analyses, they are viewed as a form of verbal takeover by a copular strategy.
12 Bengali verbs are further conjugated according toformality. There are three verb forms for 2nd person pronouns: হও (hôo, familiar), হোস (hoś, very familiar) and হন (hôn, polite). Also two forms for 3rd person pronouns: হয় (hôy, familiar) and হন (hôn, polite). Plural verb forms are exact same as singular.
One common feature ofPama–Nyungan languages, the largest family ofAustralian Aboriginal languages, is the notion of conjugation classes, which are a set of groups into which each lexical verb falls. They determine how a verb is conjugated forTense–aspect–mood. The classes can but do not universally correspond to the transitivity or valency of the verb in question. Generally, of the two to six conjugation classes in a Pama-Nyungan language, two classes are open with a large membership and allow for new coinages, and the remainder are closed and of limited membership.[8]
They are labelled by using common morphological components of verb endings in each respective class in infinitival forms. Inthe Wanman language these each correspond tola,ya,rra, andwa verbs respectively.
See also a similar table of verb classes and conjugations in Pitjantjatjara, aWati language wherein the correlating verb classes are presented below also by their imperative verbal endings-la, -∅, -ra and-wa respectively
Ngarla, a member of theNgayarda sub-family of languages has a binary conjugation system labelled:
l class
∅ class
In the case of Ngarla, there is a notably strong correlation between conjugation class and transitivity, with transitive/ditransitive verbs falling in thel-class and intransitive/semi-transitive verbs in the∅-class.
These classes even extend to how verbs are nominalized as instruments with thel-class verb including the addition of an/l/ before the nominalizing suffix and the blank class remaining blank:
