divan for two persons
匟 refers to a specific piece of furniture: a divan or couch designed for two people. Its meaning is narrow and concrete, with no clear abstract extensions.
匟 is a rare character combining the enclosure 匚 (box, container) with 亢, which likely contributes a phonetic element. The exact historical development is uncertain, but the structure suggests a container-like object, fitting the furniture meaning.
The outer 匚 looks like a box or frame, and inside is 亢. Picture a sturdy box-like couch with a high back (亢 suggests something raised) where two people can sit together.
For コウ, imagine a couple (two people) sitting on the divan, and one says "cozy, huh?" — "co" sounds like コウ, tying the reading to the two-person couch.
