What does upwell mean?
Upwell means to rise or swell upward, most often of water or another liquid, though it can also describe gas, heat, or abstract forces such as emotion. A current upwells when deep water moves toward the surface, and groundwater may upwell through permeable rock or soil. In figurative use, “feelings upwell” or “emotions upwell” suggests that strong emotions become increasingly visible or overwhelming rather than merely being named. The word is especially natural in oceanography, geology, hydrology, and environmental writing, where it describes an upward movement from below. In everyday speech, “well up” is often the more familiar phrasing, particularly for water or emotion. Upwell is nevertheless valuable because it compactly names the process of something rising, swelling, or emerging from a hidden depth while linking physical and figurative uses.

Where does upwell come from?
Upwell is an English compound formed from up and well, with the second element drawing on the older sense of a well as a source or flow of water. Its modern meaning developed from the image of material rising from below, as water does from a well, and was later extended to physical currents and figurative emotions. The word belongs to the Germanic and English compound tradition and has no regular non-English cognate family.
