better-than-expected

The term "better-than-expected" is a modern English compound, emerging from the common practice of creating adjectival phrases to describe performance metrics, particularly in business, economics, and reporting. It directly utilizes the native English comparative form "better," from Old English betera, related to the Proto-Germanic root batizô meaning "good." This is combined with the conjunction "than," from Old English þonne, and the past participle "expected," from Latin exspectare meaning "to look out for." The compound's logic is entirely transparent, literally meaning "superior to what was looked forward to," and its adoption reflects a need for concise, evaluative language in data-driven contexts.

This is a phrasal compound adjective formed from a comparative adverb ("better"), a conjunction ("than"), and a past participle ("expected"). It functions as a single lexical unit.
