ineligible

The word 'ineligible' is a straightforward negation formed in English by adding the Latin-derived negative prefix 'in-' to the adjective 'eligible.' The core, 'eligible,' traces back to the Latin verb eligere, meaning "to pick out" or "to choose," which itself is a compound of e- (a variant of ex-, meaning "out") and legere ("to gather, pick, read"). Thus, the literal sense of eligibilis was "able to be picked out." The modern abstract meaning of 'ineligible' logically follows this construction: it describes someone or something that is "not able to be chosen" due to failing to meet stipulated criteria, preserving the ancient logic of selection and exclusion inherent in its roots.

Structure: in (not) + eligible (qualified) - in: A Latin prefix meaning "not" or "without."
