Ambiguity is the property of being ambiguous, where a wor, term, notation, sign, symbol, phrase, sentence, or any other form used for communication, is called ambiguous if it can be interpreted in more than one way. Ambiguity is distinct from vagueness, which arises when the boundaries of meaning are indistinct. Ambiguity is context-dependent: the same communication may be ambiguous in one context and unambiguous in another context. For a word, ambiguity typically refers to an unclear choice between different definitions as may be found in a dictionary. A sentence may be ambiguous due to different ways of parsing the same sequence of words.
