relatum
Noun: A relatum is one of the fundamental terms in a relational statement or proposition. It is an object or entity that stands in a specific relation to another object or entity (the other relatum) within that statement. The concept is central to logic, philosophy, and semantics when analyzing the structure of relationships.
The word relatum is used in formal, academic contexts to dissect and describe the components of a relationship. A proposition expressing a relation (like "A is north of B") contains at least two relata (plural). Each participant in the relation is a relatum. * In the relation "is the parent of," the parent and the child are the two relata. * A statement defines a relationship that holds between its relata.
- In the proposition "The book is on the table," both 'the book' and 'the table' are relata of the relation "is on."
- For the relation "is taller than," if we say "Alice is taller than Bob," then Alice and Bob are the two relata.
- The philosopher analyzed the statement, identifying each relatum and the nature of the relation connecting them.
- Logical and Philosophical Analysis: In logic, a relation is defined as a set of ordered pairs (or n-tuples) of . The properties of a relation (symmetry, transitivity, etc.) are determined by how it interacts with its .
- Multiple Relata: While binary relations have two , relations can be ternary (three , e.g., "A gave B to C") or n-ary (involving number of ).
- Relation (n): The connection, association, or link that holds between two or more . (e.g., The of "between" requires three ).
- Relational (adj): Pertaining to or characterized by relations. (e.g., a database).
- Correlate (n/v): A related or complementary item; to have a mutual relationship. While similar, a often implies a reciprocal or parallel connection, whereas a is a neutral term for any member of a relation.
- Term (in a relation)
- Member (of a relation)
- Argument (in logic and mathematics)
The meaning of relatum is highly specialized and consistent. It does not have different everyday meanings. Its sole purpose is to label the positional elements within a formally expressed relationship. The plural form is relata.
- a term in a proposition that is related to the referent of the proposition
