above par
Synonym discussion
Sense: idiom/1
All four expressions describe something that surpasses a normal standard, but they differ in strength and register. 'Above par' (from golf) is a fixed idiom often used for performance or quality — it sounds a bit dated but is still readily understood. 'Better than average' is the most neutral and flexible: it works in any context from exam results to restaurant food. 'Outstanding' and 'exceptional' are stronger — they imply the performance is not just above normal but truly remarkable or rare. For example: 'Her sales figures were above par this quarter' suggests a solid improvement, while 'Her sales figures were outstanding' suggests she was the top performer in the company.
Etymology
This expression comes from the sport of golf, where 'par' is the standard number of strokes a skilled player is expected to take for a hole. Scoring 'above par' means finishing a hole in fewer strokes than that standard — a better result. The phrase moved into general English during the 19th century to describe anything surpassing the usual or expected standard.
