Etymology

un- +? ambiguous

Adjective

unambiguous (comparative more unambiguous, superlative most unambiguous)

1. clear, and having no uncertainty or ambiguity

   • An LR(k) grammar is clearly unambiguous, since the definition
     implies every derivation tree must have the same handle, and by induc-
     tion there is only one possible tree. It is interesting to point out further-
     more that nearly every grammar which is known to be unambiguous is
     either an LR(k) grammar, or (dually) is a right-to-left translatable
     grammar, or is some grammar which is translated using "both ends to-
     ward the middle." Thus, the LR(k) condition may be regarded as the most
     powerful general test for nonambiguity that is now available.
