Synonym discussion
Sense: noun/1
Expectedness, predictability, probability, likelihood, and foreseeability all relate to how confidently one can anticipate an outcome, but they differ in emphasis and context. Expectedness focuses on the quality of being regarded as likely — it is partly subjective, grounded in what people consider normal or routine. Predictability is similar but stresses the ability to foretell based on patterns or data; a predictable event is one that could have been known in advance. Probability is a more technical, often mathematical measure of chance (a 70% probability of rain). Likelihood is a less formal counterpart to probability, common in everyday speech (there is a strong likelihood of delays). Foreseeability is primarily a legal term describing whether a reasonable person could have anticipated a harm or consequence. For example, the expectedness of monsoon rains differs from the probability of an earthquake on a specific date — the former is a matter of seasonal expectation, the latter a statistical calculation.

Etymology
Formed in English from the verb expect (from Latin expectare, 'to look out for, await') plus the suffix -ness, which turns adjectives into nouns meaning 'the state or quality of being'. The adjective expected (anticipated, counted on) combined with -ness to produce expectedness by the early 19th century. The word remains fairly specialised, found mostly in formal, analytical, or technical writing.
