The phrase "grew dark" does not have a distinct etymology. It is a combination of the verb "grew", which is the past tense of "grow", and the adjective "dark", indicating the absence or depletion of light. "Grow" comes from the Middle English word "growen", which has Germanic roots and is related to the Old Norse word "groa" meaning "to grow" or "to become bigger". "Dark" comes from the Old English word "deorc", which has Proto-Germanic origins. Together, "grew dark" simply means that something became or turned dark.
