county in Shandong province
濰 is a rare kanji used primarily as a place name, specifically a county in Shandong province. Its standalone meaning is tied to that geographic reference.
濰 combines the water radical 氵 with 維, which likely contributes the sound. It is a phono-semantic compound used for a river or place name in ancient China.
The water radical 氵 suggests a river or body of water, and 維 can mean 'to tie' or 'maintain'. Imagine a river that ties together the landscape of a county in Shandong.
For イ, picture an easel (イーゼル) set up by the river in that Shandong county: easel -> イ, and the river flows past it.
