heir-requesting sacrifice

禖 is composed of the radical 示 (altar, show) and 某 (certain, obscure). 示 is a pictograph of an altar, extending to mean sacrifice or worship, while 某 serves as a pronoun for a person, implying uncertainty. Ancient people valued heirs and would perform sacrifices to heaven to pray for offspring. Since the child was yet to be born and thus unknown, 禖 represents the sacrificial ritual for seeking a child.
