to receive, to enjoy
亯 centers on receiving something beneficial and taking pleasure in it: to receive and to enjoy. The two meanings are closely linked, suggesting a welcoming acceptance.
The exact historical development of 亯 is uncertain. It visually contains 亠 (top) and a lower part resembling 日 or 曰 over 口, but this may be a modern simplification or variant. It is likely related to 享, which historically depicted a high building or offering, but the specific origin of 亯 is unclear.
Picture a person under a roof (亠) receiving a gift with a smiling mouth (口) and bright eyes (日), enjoying the moment.
For キョウ, imagine receiving a gift and shouting 'KYO!' in excitement: KYO -> キョウ, capturing the joy of receiving.
