"Geist" appears to have a common etymological background with the English term "ghost". But "ghost" in English is clearly defined as "the disembodied spirit or soul of a deceased person" Wikipedia article on Ghost whereas in German every living sentient being has a Geist, more like Spirit. Once the being dies the mind /ghost/spirit can continue to exist as a disembodied entity, then the term "Geist" has the same clear meaning as in English - that of a deceased person.
