Head Of Household
Husband, Head Of A Household, Head Of The Household, Landlord, Master
noun, の adjective
The master person isn't just a master. You have to think back to when they were making these kanji. Who was the master? It was the head of household. This head of household probably told servants what to do and was all bossy and stuff. He was the master person.
Also, this often means husband. Because, I guess the head of household back in the day was the husband. Those sexist ancient people!
しゅじん
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 人 has two on'yomi readings, here's a mnemonic to help you remember which one to use:
In Japan, tradition says the head of a household must slide down a chute in only jeans (しゅじん). Whenever you need to speak to the head of the household, they'll come sliding down a chute wearing nothing but jeans. What a sight!
きのう、ご主人とどこかへいきましたか？
