noun
A name given to a deceased person in Japanese Buddhism, typically inscribed on a grave marker or memorial tablet. Often contrasted with 戒名 (kaimyō), which is the precept name received during life or at ordination.

お墓には故人の贈り号が刻まれている。
The deceased's posthumous Buddhist name is engraved on the gravestone.
僧侶に贈り号を付けてもらった。
We had a priest bestow a posthumous Buddhist name.
戒名 is a Buddhist precept name given during life or at ordination, while 贈り号 specifically refers to a posthumous name given after death.
Compound of 贈り (okuri, 'sending off, bestowing') + 号 (gō, 'name, title'). The exact historical derivation is uncertain, but the term is conventionally associated with the Buddhist practice of assigning a special name to the deceased.
