To make something unable to function or to deprive someone of a physical or mental ability. In computing, to turn off or deactivate a feature or function.
From Old French 'desabilier,' from 'des-' (opposite of) plus 'abilier' (to make able), ultimately from Latin 'habilis' (able). The term emerged in the 15th century, initially in legal contexts.
The evolution of 'disable' from describing individual limitations to computer functions reflects how we anthropomorphize technology - we literally give machines 'abilities' so we can then 'disable' them. The computing usage has ironically made the word more common in positive contexts, as disabling unwanted features improves user experience!
