hermitage
菴 centers on a secluded dwelling: a hermitage, a small retreat where one lives simply and apart from the world.
菴 combines the plant component 艹 with 奄, which likely contributes the sound. The character originally referred to a type of plant, and later came to be used for a thatched hermitage, possibly through association with 庵.
The plant top 艹 over 奄 suggests a simple thatched roof made of plants, like a small hermitage hidden in nature.
For アン, picture an ant finding a quiet hermitage under the plants: ant -> アン, and the ant rests in the secluded retreat.
