Sense: adjective/1
All four words describe what is still present after part has been removed or used, but they differ in scope and register. 'Left' is the broadest and most common — it works for food, time, money, or abstract concepts ('any seats left?'). 'Leftover' is narrower, referring mainly to food or materials that were not consumed ('leftover pizza'). 'Outstanding' applies to tasks, payments, or issues that still need attention, not to physical objects. 'Residual' is the most formal and technical, describing small amounts that remain after a chemical, industrial, or statistical process. For everyday situations, 'left' and 'remaining' are the safest choices; 'leftover' suits casual food references; 'outstanding' fits bills or homework; 'residual' belongs in specialised writing.

Etymology
The adjective 'remaining' comes from the verb 'remain', which entered English through Old French 'remaindre', from Latin 'remānēre' — a combination of 're-' (back) and 'manēre' (to stay). The original sense was 'to stay behind'. The adjective form developed in the 1400s, carrying the idea of what stays behind after everything else has moved or been taken.
