Part of speech: adverb

Definitions

Etymology: "Bottomward" is about as transparent as English words get: it joins "bottom" to the suffix "-ward," which has been used since Old English to mark direction, as in "homeward," "backward," and "upward." Attaching that suffix to a noun for a physical low point produces an adverb meaning "toward the bottom" without any change in the base word's sense. The same pattern works with other nouns for places or positions. "Earthward" points toward the ground, "seaward" toward the sea, and "skyward" toward the sky, so "bottomward" belongs to a productive family of directional adverbs that English has long built on demand.
