溜まる

to collect
💧🪣 溜 = water 氵 + stay 留: water that stays put builds up
The kanji joins the water radical 氵 with 留 (to stay, remain). Water that stays where it is collects into a pool, and that is the meaning: to gather or accumulate. Also used for dust, stress and savings that pile up.
溜 — water 氵 + 留 (liú, stay)
A semantic-phonetic compound: the water radical 氵 gives the meaning (smooth, slippery, flowing) while 留 supplies the sound. Originally describing water flowing swiftly and smoothly, it extended to mean 'slip,' 'glide,' or 'sneak away,' as well as 'slippery' surfaces.
