## AI Etymology
incredibility comes from incredible + -ity; from Latin incredibilis, from in- ('not') + credibilis ('believable'), from credere ('to believe, trust'). Morphologically, the ending is part of the etymology: the suffix is attached to the older base named in the history, producing a later English derivative. In present English, the noun sense is "the quality of being too implausible to be believed", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as incredible, credibility, credible, and credit. Its semantic neighborhood includes implausibility, unbelievability, improbability, and incredibleness, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin credere and Proto-Indo-European *ḱred-dʰeh₁-.
