What does ambiguousness mean?
Ambiguousness is a formal noun denoting the quality of being ambiguous — that is, the state of having more than one possible meaning or interpretation, or of being difficult to understand clearly. It is derived straightforwardly from the adjective 'ambiguous' by adding the suffix '-ness', which converts qualities into nouns. In practice the word is rare: English speakers almost invariably reach for its shorter and older synonym 'ambiguity', which covers both the abstract quality and individual instances of double meaning (one may speak of 'an ambiguity in the text'). Ambiguousness, by contrast, tends to appear in analytical or academic writing when an author wishes to stress the general condition of unclarity rather than any particular instance — for example, 'the ambiguousness of the treaty's language'. It carries no strong connotation of praise or blame, though deliberate unclearness can suggest evasiveness. Writers should be aware that using ambiguousness where ambiguity is expected can read as awkward or affected, so it is best reserved for contexts where the distinction genuinely matters.
nounThe quality or state of being ambiguous; the condition of having more than one possible meaning or interpretation, or of being open to unclear understanding.
- The state or quality of being open to more than one interpretation; lack of clarity in meaning.
- Uncertainty or obscurity of intention or significance.
"The ambiguousness of the contract's wording left both parties uncertain of their obligations."
"Critics noted the ambiguousness of the poem's final stanza, which could be read as either hopeful or despairing."
"The survey's results were undermined by the ambiguousness of several of its questions."
A plural is theoretically possible but virtually never used; the word denotes an abstract quality, so it appears almost exclusively in the singular.
"The report catalogued various ambiguousnesses in the original legislation."
'Ambiguousness' is what happens when a perfectly good word — ambiguity — spawns a longer, clunkier twin that most dictionaries list but almost nobody actually uses.

Etymology of ambiguousness
Ambiguousness is formed within English from the adjective 'ambiguous' plus the suffix '-ness', following a common pattern for turning adjectival qualities into abstract nouns. The adjective 'ambiguous' itself comes from Latin 'ambiguus', meaning 'going around, wavering, doubtful', from 'ambigere' — literally 'to drive around' — formed from 'ambi-' ('both ways') and 'agere' ('to drive, do'). The Latin root also gives English words such as 'ambit', 'ambient', and 'agenda'. The noun form arose as a later derivative alongside the much earlier borrowing 'ambiguity', which came into English via Latin and French.
How ambiguousness is actually used
Formal and rare. 'Ambiguousness' is a legitimate derivative of 'ambiguous', but 'ambiguity' is overwhelmingly preferred in both British and American English across all registers. When it does appear, 'ambiguousness' tends to occur in philosophical, legal-analytical, or deliberately technical prose where the writer wants to emphasize the abstract quality itself rather than a specific instance of double meaning.
Easily confused with ambiguousness
'Ambiguity' is the standard, far more common noun for the same quality, while 'ambiguousness' is a rare variant formed directly from the adjective 'ambiguous'; they mean essentially the same thing.
