Though originally referring to a mass of creatures of some sort (such as maqSung Do' "swarm of bees"), the word's meaning is sometimes broadened and used for masses of inanimate objects (such as wolmeye' Do' "swarm of drones"). HoSDo' ("energy beings") may have formerly been HoS Do' (perhaps translated as something like "swarm of energy," with the notion of "lifeforms" or "beings" (in this case non-corporeal) implicit in the meaning of Do', but it is now considered a single inherently plural noun.
