Word Origin

From Middle English 'inabilite', from Old French 'inabilite', from Latin 'inabilitas', from 'in-' (not) + 'habilis' (able).

Usage Notes

This phrase is typically followed by 'to' + verb (e.g., 'inability to pay'). It is more formal than 'can't' or 'unable to' and is often used in written or professional contexts.
