regular language is easy to understand than context free language
almost same
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.
The regular expression for a context-free grammar that generates the keyword "keyword" is simply the word "keyword" itself.

A context-free grammar (CFG) can be converted into a regular expression by using a process called the Arden's theorem. This theorem allows for the transformation of CFG rules into regular expressions by solving a system of equations. The resulting regular expression represents the language generated by the original CFG.
Grammar that we all use, there is no other kind of grammar.
Traditional grammar is correct "textbook" grammar. Functional grammar is colloquial grammar, grammar that people use in regular conversation. For instance, people tend to say "Who are you going with?" even though that is incorrect and the correct form would be "With whom are you going?" (prepositions should always precede their objects, and "who" should be in the objective case "whom").
No, not all regular languages are context-free. Regular languages are a subset of context-free languages, but there are context-free languages that are not regular.
To convert regular grammar into a nondeterministic finite automaton (NFA), each production rule in the grammar is represented as a transition in the NFA. The start symbol of the grammar becomes the start state of the NFA, and the accepting states of the NFA correspond to the final states of the grammar. The NFA can then recognize strings that are generated by the regular grammar.
No, not every deterministic context-free language is regular. While regular languages are a subset of deterministic context-free languages, there are deterministic context-free languages that are not regular. This is because deterministic context-free languages can include more complex structures that cannot be captured by regular expressions.
Does regular English is grammar free? Different question, same answer.
It means "I am regular" in the context that "I am okay" or I am fine.
