Ludwig Wittgenstein is known for his theory of meaning as use, which states that the meaning of a word is determined by the way it is used in language.

Denotation refers to the literal meaning of a word, while connotation refers to its emotional or associative meaning. For example, the word "home" denotes a place where one lives, while its connotation may include feelings of comfort, security, and belonging.

Alfred Tarski is known for his theory of meaning as truth-conditions, which states that the meaning of a sentence is determined by the conditions under which it is true.

Analytic statements are true by definition, while synthetic statements are true by experience. For example, the statement "All bachelors are unmarried" is an analytic statement because it is true by definition of the term "bachelor". The statement "The grass is green" is a synthetic statement because it is true by experience.

A.J. Ayer is known for his theory of meaning as verification, which states that the meaning of a statement is determined by the way it can be verified.

A priori knowledge is knowledge that is known independently of experience, while a posteriori knowledge is knowledge that is acquired through experience. For example, the statement "All bachelors are unmarried" is a priori knowledge because it is known independently of experience. The statement "The grass is green" is a posteriori knowledge because it is acquired through experience.

Ludwig Wittgenstein is known for his theory of meaning as a family resemblance, which states that the meaning of a word is determined by its similarities to other words in the same family.

Necessary truths are truths that are true in all possible worlds, while contingent truths are truths that are true in some possible worlds but not others. For example, the statement "All bachelors are unmarried" is a necessary truth because it is true in all possible worlds. The statement "The grass is green" is a contingent truth because it is true in some possible worlds but not others.

Wittgenstein is known for his theory of meaning as a cluster concept, which states that the meaning of a word is determined by its various uses in different contexts.

Internalism is the view that the meaning of a word is determined by the speaker's mental states, while externalism is the view that the meaning of a word is determined by factors outside of the speaker's mental states. For example, an internalist might argue that the meaning of the word "red" is determined by the speaker's mental image of the color red, while an externalist might argue that the meaning of the word "red" is determined by the physical properties of red objects.

Jürgen Habermas is known for his theory of meaning as a social practice, which states that the meaning of a word is determined by the way it is used in social interaction.

Semantic meaning is the meaning of a word or phrase in isolation, while pragmatic meaning is the meaning of a word or phrase in context. For example, the semantic meaning of the word "dog" is a four-legged mammal, while the pragmatic meaning of the word "dog" in the sentence "The dog is barking" is the animal that is making the barking sound.

Ludwig Wittgenstein is known for his theory of meaning as a form of life, which states that the meaning of a word is determined by the way it is used in the context of a particular form of life.

Referential uses of language are used to refer to objects or events in the world, while attributive uses of language are used to describe or attribute properties to objects or events. For example, the sentence "The cat is on the mat" is a referential use of language because it refers to a particular cat and a particular mat. The sentence "The cat is black" is an attributive use of language because it attributes the property of being black to the cat.

Wilfrid Sellars is known for his theory of meaning as a network of concepts, which states that the meaning of a word is determined by its relationships to other words in the language.
