long-dead

The compound adjective 'long-dead' is a transparent combination of two ancient Germanic roots. 'Long' originates from the Proto-Germanic langaz, conveying the concept of extended duration, while 'dead' stems from daudaz, denoting the state of having died. Their union in English follows a straightforward compounding pattern, common in Germanic languages, where the first element modifies the second. The term's literal logic—'dead for a long time'—has been seamlessly extended to describe not only deceased beings but also abstract entities like customs, languages, or civilizations that ceased to exist long ago.

Functions as an adjective/adverb meaning 'extending far in time'. - dead: From Old English dēad, of Germanic origin; related to Dutch dood and German tot.
