Definition

  1. n. the state of being unable to do something; lack of capacity or skill

Structure
in <not>ability <capacity>
Etymology

The word "inability" combines the Latin-derived prefix "in-" (meaning "not") with the noun "ability" (from Latin "habilitas," meaning "capacity or skill"). The prefix "in-" negates the root, transforming "ability" into its opposite—a lack of capability. This logical construction reflects how Latin prefixes were systematically applied to roots in English to create antonyms.
