## What is the extension of a predicate?

The “extension” of a predicate (relative to an interpretation) is simply **the collection of all things to which it truly applies**. If the universe of discourse happens to be finite, and indeed rather small, the extension of predicates can be given by means of a table.

## Is a predicate a set?

In set theory with excluded middle, **predicates are understood to be characteristic functions or set indicator functions** (i.e., functions from a set element to a truth value). Set-builder notation makes use of predicates to define sets.

## Is an extension to propositional logic?

**It should be viewed as an extension to propositional logic**, in which the notions of truth values, logical connectives, etc still apply but propositional letters(which used to be atomic elements), will be replaced by a newer notion of proposition involving predicates and quantifiers.

## What is an extension logic?

extension, in logic, **correlative words that indicate the reference of a term or concept**: “intension” indicates the internal content of a term or concept that constitutes its formal definition; and “extension” indicates its range of applicability by naming the particular objects that it denotes.

## What is the extension of a set?

The extension of an object in abstract algebra, such as a group, is the underlying set of the object. The extension of a set is **the set itself**. That a set can capture the notion of the extension of anything is the idea behind the axiom of extensionality in axiomatic set theory.

## What is an example of extension?

The definition of an extension is an addition such as to a building, an extra phone line connected to the main line or an extra amount of time given to someone to pay a debt. An example of an extension is **adding a second story to a single story house**.

## Can a term have an extension but no intension?

## What is the difference between intention and extension?

intension and extension, in logic, correlative words that indicate the reference of a term or concept: **“intension” indicates the internal content of a term or concept that constitutes its formal definition; and “extension” indicates its range of applicability by naming the particular objects that it denotes**.

## What are the differences between extension and intension in meaning?

Intension refers to the logical or definitional conditions that specify the set of all possible things a word or phrase could describe, while extension refers to the set of all actual things the word or phrase describes.

## What is meant by meaning extension in semantic?

The extension of semantic meaning refers to **extend a word’s meaning according to the context and logical relations and select an exact word in the target language, so as to make the translation more natural, native and smooth**.

## What is an example of logical extension?

## Is denotation the same as extension?
