human-caused

The compound adjective 'human-caused' is a modern formation following a transparent English syntactic pattern. The first element, 'human', traces back to Latin humanus, which itself derives from homo, meaning 'man' or 'human being'. The second element, 'caused', originates from Latin causa, meaning a reason or motive, which evolved into a verb meaning to make something happen. When combined, the term literally means "caused by humans," directly linking the agent ('human') to the resultant state ('caused'). This logical construction emerged prominently in the 20th and 21st centuries within scientific and environmental discourse to explicitly attribute phenomena, especially ecological changes or disasters, to anthropogenic activity, distinguishing them from natural events.

Structure: human + caused - human: From Latin humanus (of or belonging to man), related to homo (man). Functions as a noun used attributively to specify the agent. - caused: From Latin causa (reason, cause). The past participle form of the verb 'cause', functioning to indicate the state of being brought about.
