better-than-average

The compound adjective "better-than-average" is a modern English construction built from three distinct and ancient components. "Better" originates from the Proto-Germanic comparative form batizô, linked to the idea of improvement. "Than" is a conjunction of comparison with roots in Old English demonstratives. "Average" has a more circuitous history, entering English via maritime law to denote a financial loss shared among merchants, which evolved mathematically to signify a mean value. The phrase's logic is transparently comparative, literally meaning "superior to the mean," and reflects a quantitative mindset where individual or group performance is evaluated against a statistical norm.
