cottage
葊 centers on a simple dwelling: a cottage or small rustic shelter.
葊 is a rare character. It combines the grass radical 艹 with 弇, which likely contributes a phonetic element. The exact historical development is uncertain.
The grass top 艹 suggests a thatched roof, and the lower part 弇 looks like a small enclosed space. Picture a simple cottage with a grassy roof and a cozy room inside.
For アン, imagine an ant living in a tiny grass cottage: ant -> アン, and the ant's home is the cottage.
