This one, my eldest cousins (“my paternal eldest aunt’s kids” to be specific) calls my mother (their “aunt”) and my aunts (“my paternal uncle’s wife”) this word.

Also, “막내엄마” /mag nae ŏm ma/: Youngest aunt. (English transliteration “Youngest Mom”).

I'm sorry it took much longer, I realize there are probably so many others that I’m missing here which I probably am. If I’ve missed any other direct bloodlines, please feel free to add it in the comments section. Please feel free to share. 🙂
