dropping
瀝 centers on liquid falling in drops: the act of dripping or dropping, often used for water or other fluids.
瀝 combines 氵 (water) with 歷, which likely contributes the sound レキ and may suggest a process or passage, together giving the idea of water passing drop by drop.
Water 氵 beside 歷: imagine a historical timeline where each event is a single drop of water falling, one after another.
For レキ, picture a leaky faucet where each drop makes a 'recky' sound as it hits the sink: recky -> レキ, and the drops keep falling.
