In general, finite state machines can model regular grammars. Deterministic finite automata can represent deterministic context-free grammars. Non-deterministic finite automata can represent context-free grammars.
The grammar is said to be operator precedence grammar, if its right hand side of its production should not have the Empty production or two non-terminal should not be adjacent to each other, then we call it as operator precedence grammar The grammar is said to be operator precedence grammar, if its right hand side of its production should not have the Empty production or two non-terminal should not be adjacent to each other, then we call it as operator precedence grammar

A context-free grammar can generate languages that regular grammars cannot, as it allows for the use of non-terminal symbols in productions. Regular grammars, on the other hand, are less powerful and can only generate regular languages, which are a subset of context-free languages. Context-free grammars are more expressive and have more flexibility in rule definitions compared to regular grammars.
regular language is easy to understand than context free language
almost same
we use context free grammer in compiler consctrtion to cheack the validati of input in parsing.
The term inherently ambiguous is used in computer science. The term ambiguous grammar means that the grammar has no context and that there is a string which can be generated by the grammar in more than one way. Inherently ambiguous means that all context free grammar in the language is ambiguous.
A context-sensitive grammar is a formal grammar type where the production rules are written in the form αAβ → αγβ, where α and β are strings of terminals and nonterminals, A is a nonterminal, and γ is a nonempty string. These grammars are more powerful than context-free grammars and can handle languages that require context to be fully defined. They are often used in linguistic analysis and natural language processing.
An antonym for context would be 'grammar' or 'reading'.
To show that a grammar is LALR but not SLR, you can construct a parsing table for the grammar and demonstrate that there are conflicts present in the SLR parsing table that are resolved in the LALR parsing table. Specifically, LALR parsers have larger look-ahead sets than SLR parsers which can resolve these conflicts. In other words, LALR parsers are able to distinguish between more parser states compared to SLR parsers, allowing them to handle more complex grammars.
Most word processors have Grammar Check in addition to Spell Check. Look for it in your drop down menu. Grammar Check will highlight errors and note suggested changes which you can either Change or Ignore.
