Can a context-free grammar be ambiguous?
If a context free grammar G has more than one derivation tree for some string w ∈ L(G), it is called an ambiguous grammar. There exist multiple right-most or left-most derivations for some string generated from that grammar.
How ambiguity is avoided in grammar?
Use commas correctly!
Commas exist primarily to resolve syntactic ambiguity. If you're worried that your sentences are too ambiguous, try working on your grammar and punctuation, especially when it comes to commas.
What is eliminating ambiguity?
Ambiguity elimination makes the sentence clear and readable. A sentence is grammatically ambiguous if it can produce more than one parse tree for a particular grammar.
