The quality or state of being ambiguous; doubtfulness or uncertainty, particularly as to the signification of language, arising from its admitting of more than one meaning; an equivocal word or expression.
The goal is to live a full, productive life even with all that ambiguity. No matter what happens, whether the cancer never flares up again or whether you die, the important thing is that the days that you have had you will have lived. Gilda Radner
There is no greater impediment to the advancement of knowledge than the ambiguity of words. Thomas Reid
I have always felt that a woman has the right to treat the subject of her age with ambiguity until, perhaps, she passes into the realm of over ninety. Then it is better she be candid with herself and with the world. Carl Sandburg
