Etymology
瘻 combines 疒 (sickness) with 婁, which likely contributes the sound. The character originally referred to a hunchback or swelling, later extended to fistula in medical contexts. The exact historical development of the inner component is uncertain.
Meaning mnemonic
The sickness enclosure 疒 wraps around 婁, which looks like a twisted, knotted shape. Picture a diseased, tunnel-like passage forming under the skin, like a fistula connecting two areas.
Reading mnemonic
For ル, imagine a loop-shaped fistula: loop -> ル, and the sickness enclosure contains this looping passage.
