Frequently Asked Questions

Does ambiguous have the same meaning as unclear?

Both ambiguous and unclear can describe something that is difficult to understand because it is not shown or expressed clearly. However, ambiguous most often describes something that is unclear specifically because it can be understood in more than one way, or because it has more than one possible meaning.

What is the difference between ambiguous and ambivalent?

The Latin prefix ambi-, meaning "both," begins both ambiguous and ambivalent. Ambivalent relates to multiple and contradictory feelings (the second portion of this word comes from the Latin valēre, meaning "to be strong, be effective, have worth"). Ambiguous, on the other hand, often describes something with several possible meanings that create uncertainty. The -ig- in ambiguous comes ultimately from Latin agere ("to drive, to lead"); paired with ambi-, it suggests movement in two directions at once, and hence, a wavering or uncertainty.

What is the noun form of ambiguous?

Ambiguous is an adjective. The noun form related to this word may be either ambiguity or ambiguousness. The adverb is ambiguously.
