What is the difference between grammar, syntax, and discourse? Are there any other categories?
Any help is much appreciated!
Wikipedia:
In linguistics, grammar is the set of structural rules governing the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology, syntax, and phonology, often complemented by phonetics, semantics, and pragmatics.
In linguistics, syntax (/ˈsɪnˌtæks/) is the set of rules, principles, and processes that govern the structure of sentences in a given language, specifically word order. The term syntax is also used to refer to the study of such principles and processes The goal of many syntacticians is to discover the syntactic rules common to all languages.
Discourse analysis (DA), or discourse studies, is a general term for a number of approaches to analyze written, vocal, or sign language use, or any significant semiotic event.
The objects of discourse analysis—discourse, writing, conversation, communicative event—are variously defined in terms of coherent sequences of sentences, propositions, speech, or turns-at-talk. Contrary to much of traditional linguistics, discourse analysts not only study language use 'beyond the sentence boundary', but also prefer to analyze 'naturally occurring' language use, and not invented examples. Text linguistics is a closely related field. The essential difference between discourse analysis and text linguistics is that discourse analysis aims at revealing socio-psychological characteristics of a person/persons rather than text structure
=============
So think of grammar as word, phrases & clauses; syntax as sentences; discourse analysis as larger units.
