Morphology

capillary + water

The meaning is directly compositional: it denotes water associated with or moved by capillaries/capillary action, so a learner who knows 'capillary' (thin tube/capillary action) and 'water' can infer water held in small pores. Although it is a technical soil‑science term, the noun‑noun combination follows regular, cross‑linguistically common composition patterns and is therefore predictable from the constituents.

Etymology

The noun capillary water uses the image of water moving through very small spaces called capillaries, like the way liquid climbs a paper towel. So, capillary water means the thin layer of 'held' water around soil grains that can still move to plant roots after extra water has drained away.
