In computer science, an ambiguous grammar is a context-free grammar for which there exists a string that can have more than one leftmost derivation or parse tree. [1] [2] Every non-empty context-free language admits an ambiguous grammar by introducing e.g. a duplicate rule.
Rules other than phonetic can be used when the meaning of the noun is known or at least its semantic group is recognized. In this category obvious examples are proper names of people, or nouns designating nationality, profession, etc. Nouns referring to animals and birds are always specific to their biological gender, and often occur in pairs the same way as we have cow and bull in English.
