Michael Alexander Kirkwood Halliday was a British-Australian linguist who developed the influential systemic functional linguistics model. He had two famous theories: 1) that language is a social semiotic system, with text and context influencing registers and social structures, and 2) that linguistics involves the social action and cooperation of language. Halliday's views influence critical linguistics and critical discourse analysis, including seeing text as a sociosemantic process unified with context, and analyzing language use through a critical lens relating text and context.
