noun
enshrined deity of a subordinate shrine
A deity enshrined in a branch or subordinate shrine, often one that has been divided from a main shrine's deity.
この小さな祠には、本社から分霊された枝神が祀られている。
In this small shrine, a branch deity divided from the main shrine is enshrined.
分霊 refers to the act of dividing a deity's spirit or the divided spirit itself, while 枝神 specifically refers to the deity enshrined in the branch shrine.
Compound of 枝 (branch) and 神 (deity). The exact historical derivation is uncertain, but the term likely arose in the context of Shinto shrine networks where a main shrine's deity is shared with branch shrines.
