The compound adjective "stronger-than-expected" is a modern analytical construction, built from fundamental Germanic and Latinate elements. Its core, "strong," is an ancient Germanic word denoting physical power, which combined with the native comparative suffix "-er" and the conjunction "than" establishes a relational framework. This framework is completed by "expected," a verb of Latin origin meaning 'to look out for,' which, in its participial form "-ed," describes a state of having been anticipated. The entire phrase thus logically builds its meaning from a comparison between an actual degree of strength and a prior mental projection of likelihood, perfectly illustrating how English flexibly combines its inherited and borrowed resources to create precise descriptive terms.
