🪣 溜まる (tamaru) = to accumulate; 溜まり = its noun form: what has piled up or gathered
溜まる means to build up or pile up, as with dust or unpaid bills. The noun 溜まり names the thing or place where stuff has collected, which is why it also covers arrears.
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.
