ambiguous grammar

You do not have to worry about backtracking and action side effects that may occur with an ambiguous grammar.
你不需要担心一个模糊语法可能的回溯和动作的副作用。
This grammar is ambiguous; yacc can't figure out what's going on.
该语法是不明确的；所以 yacc 无法指出接下来将做什么。
Some sentences have more than one structure, that is to say , these sentences are ambiguous. Context-free grammar can effectively express ambiguity, but it cann't resolve the ambiguity.
很多句子有一个以上的结构，即这些句子是有歧义的，上下文无关语法可以有效地表示这种歧义，但是它没有提供手段来消解歧义。
