Case marking is the process of assigning grammatical case values to dependent nouns for the type of relationship they bear to their heads. Usually a language is said to "have cases" only if nouns change their form (nouns decline) to reflect their case.
Natural Language
In the UNLarium framework, case marking is defined through S-rules in the following format:
<SYNTACTIC ROLE>(<CASE>);
Where:
- <SYNTACTIC ROLE> is the syntactic role (VA, VC, VS, VH, etc) of the case-marked term in relation to the head; and
- <CASE> is the grammatical case to be assigned.
Examples
- VS(NOM);
- assigns the nominative case (NOM) to the specifier of the verb (VS)
- VC(ACC);
- assigns the accusative case (ACC) to the complement of the verb (VC)
Observations
- Conditional case-marking
- Conditional case-marking may be stated by stating the left side of the s-rule and coindexing it to the right side:
- VC(DAT); (unconditional case-marking: assign the dative case (DAT) to the complement of the verb);
- VC(PP):=VC(DAT); (conditional case-marking: assign the dative case (DAT) to the complement of the verb (VC) if it is a PP);
- VC([make];NP):=VC(ACC); (conditional case-marking: assign the accusative case (ACC) to the complement of the verb (VC) whose lemma is "make").
- Complex case-marking
- A single case-marking rule may contain several case-marking operations:
- VS(NOM)VC(ACC)VA(OBL); (assign the nominative case to the specifier of the verb, the accusative case to the complement of the verb, and the oblique case to the adjunct to the verb)
- Case-unmarking
- Assigned cases may be deleted through "-", but only in conditional case-marking rules (i.e., when the left side of the rule is stated and coindexed to the right side)
- VC(PP,ACC):=VC(-ACC);
- The symbol ^ is used for negation and to control infinite recursion
- VC(^NOM):=VC(NOM); (assign the nominative case to the complement of verb if it does not have the nominative case)
