noun
missus; wife (of a shopkeeper, landlord, etc.)
Familiar, somewhat old-fashioned term for a married woman, especially the wife of a shopkeeper, landlord, or master. Originally an honorific, now used in casual or friendly address. Often written in kana.
隣のおかみさんがいつも親切にしてくれる。
The missus next door is always kind to me.
あの店のおかみさんはとても気
The wife of that shop is very friendly.
Derived from 御上 (okami, 'honorable above') with the honorific さん, originally a respectful term for a superior's wife. The exact historical development is uncertain.
