Equative case¶
The equative case (abbreviated ) is a grammatical case prototypically expressing the standard of comparison of equal values ("as… as…").
Core Idea¶
Equative case is treated here as the recurring socialscienceshumanitiesarts identity summarized by this source-grounded definition: The equative case (abbreviated ) is a grammatical case prototypically expressing the standard of comparison of equal values ("as… as…"). The equative case (abbreviated ) is a grammatical case prototypically expressing the standard of comparison of equal values ("as… as…"). The equative case has been used in very few languages in history. It was used in the Sumerian language, where it also took on the semantic functions of the essive case ("in the capacity of…") and similative case ("like a…").
Scope of Application¶
-
Documented setting. It was used in the Sumerian language, where it also took on the semantic functions of the essive case ("in the capacity of…") and similative case ("like a…").
-
Documented setting. The equative case has been used in very few languages in history.
-
Documented setting. It is rare and highly specialized, used exclusively to denote the height or level of an object.
-
Documented setting. The equative case (abbreviated ) is a grammatical case prototypically expressing the standard of comparison of equal values ("as… as…").
-
Documented setting. In Sumerian, the equative was formed by adding the suffix -gin 7 to a noun phrase, for example.
Clarity¶
A clear use of Equative case names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is The equative case (abbreviated ) is a grammatical case prototypically expressing the standard of comparison of equal values ("as… as…").
Manages Complexity¶
Equative case compresses multiple socialscienceshumanitiesarts details into a stable diagnostic relation. The source shows both the central mechanism—the equative case is also found subdialectally in the Khalkha dialect of Mongolian, where it can be formed by adding the suffixes -цаа [tsaa], -цоо [tsoo], -цээ [tsee] or -цөө [tsöö], depending on the vowel harmony of the noun.—and the practical consequence—the equative case has been used in very few.
Abstract Reasoning¶
- Type the carrier. Identify the socialscienceshumanitiesarts entities to which the claim applies.
- State the relation. Use the source-grounded identity: The equative case (abbreviated ) is a grammatical case prototypically expressing the standard of comparison of equal values ("as… as…").
- Check operation and conditions. In Ossetic, it is formed by adding the suffix -ау [aw].
- Demand recognition evidence. In Archi, a Northeast Caucasian language, the equative case is indicated by the case marker -qʼdi.
- Test variation.
Knowledge Transfer¶
Within the home domain. Knowledge about Equative case transfers literally when a new case preserves the same carrier type, relation, and recognition test. It was used in the Sumerian language, where it also took on the semantic functions of the essive case ("in the capacity of…") and similative case ("like a…"). The equative case has been used in very few languages in history. Beyond the home domain. No canonical parent is asserted for Equative case.

Neighborhood in Abstraction Space¶
Equative case sits in a sparse region of the domain-specific corpus (68th percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
