thread
縷 centers on a single thin strand: a thread. It can refer to literal thread or to something thread-like, such as a slender line or a detailed, continuous account.
縷 combines 糸 (thread) with 婁, which likely contributes the sound and may have originally depicted something tied or bound, reinforcing the thread idea.
The left side 糸 is thread, and the right side 婁 looks like a spool or a tied bundle. Picture a single thread being pulled from a spool: 縷 is that thread.
For ル, imagine a thread looping around a spool: loop -> ル, and the thread winds around.
