WebDec 16, 2024 · There's a cool theorem from Don Knuth that shows that a language has an LR (k) grammar for some k if and only if it has an LR (1) grammar. So in that sense, the LR (k) languages are "languages for which you can make an LR (1) grammar." Then there's the deterministic context-free languages (DCFLs), which are languages for which you can … Webchomsky hierarchy in plain english. I'm trying to find a plain (i.e. non-formal) explanation of the 4 levels of formal grammars (unrestricted, context-sensitive, context-free, regular) as set out by Chomsky.
