Something that terminates or ends; in astronomy, the boundary between light and dark portions of a celestial body.
From Latin 'terminare' meaning 'to limit, bound, end' plus the agent suffix '-ator'. Originally used in scientific contexts before gaining popular culture significance through science fiction.
While most people know this word from the famous movie franchise, astronomers have used 'terminator' for centuries to describe the moving shadow line on the Moon and planets. This astronomical terminator is actually the best time to observe lunar craters because the shadows create dramatic contrast.
The franchise's T-800 character and 'Terminator' branding are coded masculine despite androids having no sex; cultural association of killing/destruction with male aggression.
If using in AI/robot contexts, avoid gendered language; refer to agents by function, not gendered character archetypes.
