name of Chinese river
濂 is a rare kanji used primarily as the name of a Chinese river. Its standalone meaning is tied to that specific geographical reference and has no broader conceptual center.
濂 combines the water radical 氵 with 廉, which likely contributes the sound. The character was created to name a specific river, and its historical development beyond that is uncertain.
The water radical 氵 beside 廉 suggests a river name. Picture a sign beside a Chinese river with the character 濂 written on it, marking the water's identity.
For レン, imagine a lens (レンズ) floating on the river named 濂: lens -> レン, and the clear lens helps you read the river's name.
