Surface Forms

headwaters plural

Morphology

headwaters = headwater (transparent) = head + water + s

Formed from the clear compound 'head' + 'water' with a plural '-s'; the meaning 'sources of a river' is directly derivable.

Etymology

Headwaters comes from head ('top' or 'beginning') and waters ('river water'). It means the place where a river or stream first starts to flow, so the headwaters are the river's source.
