Synonym discussion

Sense: adjective/1

All five words relate to having more than what is needed, but they differ in scope and typical use. 'Extra' is the most versatile and neutral — it works in almost any context ('an extra chair', 'extra money'). 'Additional' is more formal and emphasises adding to an existing amount ('additional charges apply'). 'Surplus' is formal and often used in business or economic contexts, suggesting more than necessary ('surplus stock'). 'Leftover' specifically refers to what remains after use — common with food ('leftover pizza') but rarer with objects. 'Reserve' implies something deliberately kept for future need ('reserve tank of fuel'), carrying a stronger sense of planned storage than 'spare'. For everyday objects you keep as backups (keys, tyres, batteries), 'spare' is the most natural choice.

Etymology

Old EnglishMiddle EnglishModern English

From Old English 'sparian' meaning to refrain from harming, to be lenient, or to leave unharmed. This root is related to Old High German 'sparon' (to spare, to save) and Old Norse 'spara' (to spare, to save). The sense of 'extra' or 'surplus' developed around the 1500s, moving from the idea of 'saved from use' to 'available for use'. The adjective sense of 'thin, lean' emerged in the 1700s, perhaps based on the idea of a frugal or minimal physique.
