overheated

the word "overheated" is a modern english compound formed from native germanic elements. the prefix "over," with its sense of excess, is combined with the verb "heat," derived from the old english noun for hotness. the adjectival suffix "-ed" is appended to indicate the resulting state. the term's literal application to physical temperature provided a clear metaphorical pathway to describe economic conditions exhibiting excessive, unsustainable activity, and later, to characterize emotional states of excessive agitation. this evolution demonstrates a common pattern where a concrete physical description is extended to abstract social and psychological domains.
