Semantics is the branch of linguistics that studies the meaning of words, phrases, and sentences.

Synonymy (words with similar meanings), antonymy (words with opposite meanings), and hyponymy (words that are more specific than other words) are all examples of semantic relations.

Pragmatics is the branch of linguistics that studies how language is used in context, including the speaker's intention, the hearer's interpretation, and the social and cultural context of the interaction.

Deixis (words that refer to the speaker, hearer, or context), presupposition (information that is assumed to be true in a conversation), and implicature (information that is communicated indirectly) are all examples of pragmatic phenomena.

Implicature is the meaning of a word or phrase that is not explicitly stated but is implied by the context.

Stating a fact, asking a question, and making a request are all examples of speech acts, which are actions that are performed through language.

Syntax is the branch of linguistics that studies the rules that govern how words and phrases can be combined to form sentences.

A noun must agree with its verb in number, a sentence must have a subject and a verb, and a preposition must be followed by a noun phrase are all examples of syntactic rules.

Anthropological linguistics is the branch of linguistics that studies the relationship between language and culture.

Code-switching (switching between languages or dialects in the same conversation), dialect variation (differences in language use between different regions or social groups), and language death (the disappearance of a language) are all examples of sociolinguistic phenomena.

Psycholinguistics is the branch of linguistics that studies the relationship between language and the mind.

Aphasia (a language disorder caused by damage to the brain), Broca's aphasia (a type of aphasia that affects speech production), and Wernicke's aphasia (a type of aphasia that affects language comprehension) are all examples of psycholinguistic phenomena.

Historical linguistics is the branch of linguistics that studies the history of language.

Sound change (changes in the pronunciation of words over time), grammatical change (changes in the grammar of a language over time), and lexical change (changes in the vocabulary of a language over time) are all examples of historical linguistic phenomena.

Sociolinguistics is the branch of linguistics that studies the relationship between language and society.
