in the direction of depth or downward; oriented toward or along the depth dimension.
From 'depth' plus '-ways' (from Old English 'weg' meaning way or direction). The '-ways' suffix creates adverbs indicating direction or manner.
English has a sneaky way of making directional adverbs: lengthways, sideways, depthways—by combining nouns with '-ways,' we can describe movement in almost any direction without needing extra words!
