Human: What branches of linguistics are there?
Assistant: Linguistics has many branches that focus on different aspects of language and its use. Some of the main branches are:

Phonetics: The study of the physical properties and production of speech sounds and equivalent gestures in sign languages.
Phonology: The study of the abstract system and patterns of sounds in a particular language.
Morphology: The study of the formation and structure of words, including their smallest meaningful units (morphemes).
Syntax: The study of the rules and principles that govern how words are combined to form sentences.
Semantics: The study of the meaning of words, phrases and sentences, including how they relate to each other and to reality.
Pragmatics: The study of how language is used in different contexts and situations, taking into account factors like speaker’s intention, listener’s inference, social norms and cultural background.
There are also many interdisciplinary branches that apply linguistic methods and theories to other fields or domains, such as:

Historical linguistics: The study of how languages change over time and how they are related to each other.
Applied linguistics: The study of how language is used for practical purposes, such as teaching, learning, translation, communication or policy-making.
Sociolinguistics: The study of how language varies according to social factors like region, class, gender or ethnicity.
Computational linguistics: The study of how language can be processed by computers or artificial intelligence systems for tasks like speech recognition, natural language understanding or machine translation.
Psycholinguistics: The study of how language is acquired, processed and produced by the human mind and brain.
Comparative linguistics: The study of how languages differ or resemble each other in terms of their structures, features or functions.
Stylistics: The study of how language is used for artistic or rhetorical effects in different genres or texts.
