Synonym discussion
Sense: noun/1
Both 'surprise' and 'unexpectedness' refer to things that were not anticipated, but they differ in focus. 'Surprise' is the more common, everyday word and can refer either to the unexpected event itself ('What a surprise!') or to the feeling it creates. 'Unexpectedness' is more formal and describes the quality or nature of a situation rather than the emotional reaction — you would say 'the unexpectedness of the plot twist' in a book review, not 'the surprise of the plot twist'. 'Unpredictability' is different again: it suggests that something cannot be known in advance at all, not just that it was not expected on a particular occasion. For example, the weather has unpredictability, but a single sudden rain shower has unexpectedness.

Etymology
Formed in English from the adjective 'unexpected' (un- 'not' + expected, the past participle of 'expect') and the suffix '-ness', which turns adjectives into nouns meaning 'the quality or state of being'. The root verb 'expect' came into Middle English from Latin 'expectare' (to look out for), made up of ex- 'out' and spectare 'to look.'
