| '''Agreement''' or '''concord''' is a form of cross-reference between different parts of a sentence or phrase. Agreement happens when a word changes form depending on the other words it relates to. In the UNL<sup>arium</sup> framework, agreement is defined through [[S-rule]]s. Agreement is not informed in UNL.

| == Syntax ==
| |
| Agreement is defined through [[S-rule]]s in the following format:
| |
| | |
| <SYNTACTIC ROLE>(+<AGREEMENT>);
| |
| | |
| Where:<br />
| |
| *<SYNTACTIC ROLE> is the [[Syntactic roles|syntactic role]] (VA, VC, VS, VH, etc) of the constituent in relation to the head; and
| |
| *<AGREEMENT> is the agreement to be assigned, and may assume the following values:
| |
| **ANUM = assigns number (if the constituent assigns number value to the head)
| |
| **AGEN = assigns gender (if the constituent assigns gender value to the head)
| |
| **APER = assigns person (if the constituent assigns person value to the head)
| |
| **ACAS = assigns case (if the constituent assigns case value to the head)
| |
| **ATNS = assigns tense (if the constituent assigns tense value to the head)
| |
| **RNUM = receives number (if the constituent receives number value from the head)
| |
| **RGEN = receives gender (if the constituent receives gender value from the head)
| |
| **RPER = receives person (if the constituent receives person value from the head)
| |
| **RCAS = receives case (if the constituent receives case value from the head)
| |
| **RTNS = receives tense (if the constituent receives tense value from the the head)
| |
| | |
| == Examples ==
| |
| ;VS(+ANUM);
| |
| :number agreement: the verb agrees with its specifier in number (i.e., the specifier of the verb assigns number to the verb)
| |
| ;NA(+RGEN);
| |
| :gender agreement: the adjunct agrees with the noun in gender (i.e., the adjunct receives gender from the noun)
| |
| | |
| == Observations ==
| |
| ;Conditional agreement
| |
| :Conditional agreement may be stated by defining the left side of the s-rule and coindexing it to the right side:
| |
| :*NA(+RGEN); (unconditional agreement: the adjunct always receives the gender from the noun);
| |
| :*NA(ADJ):=NA(+RGEN); (conditional agreement: the adjunct receives the gender from the noun if adjective);
| |
| :*NA(^PP):=NA(+RGEN); (conditional agreement: the adjunct receives the gender from the noun if not a prepositional phrase);
| |
| :*NA(GEN;):=NA(+RGEN); (conditional agreement: the adjunct receives the gender from the noun if the noun has the feature gender (GEN);
| |
| ;Complex agreement
| |
| :A single agreement rule may contain several agreement operations:
| |
| :*VS(+ANUM,+APER,+AGEN); (the specifier of the verb assigns number, person and gender to it)
| |
| :*NS(+RNUM,+RPER,+RGEN)NA(+RNUM,+RPER,+RGEN); (the specifier and the adjunct of the noun receives number, person and gender from it)
| |
| ;Use of "+"
| |
| :As rules are conservative (i.e., features are preserved unless explicitly deleted), the use of "+" is actually optional:
| |
| :*VS(+RNUM); is the same as VS(RNUM);
| |
| ;Feature removal
| |
| :Agreement features may be deleted through "-"
| |
| :*NA(-RGEN); (delete "receive gender" from all noun adjuncts)
| |
| :*NA(PP):=NA(-RGEN); (delete "receive gender" from all noun adjuncts that have the feature PP)
| |
| ;The symbol '''^''' is used for negation and to control infinite recursion:
| |
| :*NA(^RGEN):=NA(+RGEN); (the adjunct receives the gender from the noun if it does not have the feature "receive gender")
| |
