Indexed grammars are a generalization of context-free grammars in that nonterminals are equipped with lists of flags, or index symbols.
The language produced by an indexed grammar is called an indexed language.
produced by an indexedgrammar is called an indexed language. In contemporary publications following Hopcroft and Ullman (1979), an indexedgrammar is formally...

Indexed languages are a class of formal languages discovered by Alfred Aho; they are described by indexedgrammars and can be recognized by nested stack...
as a grammar, or as a grammar book. A reference book describing the grammar of a language is called a "reference grammar" or simply "a grammar". A fully...

In formal language theory, an LL grammar is a context-free grammar that can be parsed by an LL parser, which parses the input from Left to right, and...

In computer science, a grammar is informally called a recursive grammar if it contains production rules that are recursive, meaning that expanding a non-terminal...
Cognitive grammar is a cognitive approach to language developed by Ronald Langacker, which hypothesizes that grammar, semantics, and lexicon exist on a...
input: 1 + 1 The two LR(0) parsing tables for this grammar look as follows: The action table is indexed by a state of the parser and a terminal (including...
Generative grammar is a theoretical approach in linguistics that regards grammar as a domain-specific system of rules that generates all and only the...

typical way of defining head grammars is to replace the terminal strings of CFGs with indexed terminal strings, where the index denotes the "head" word of...
