Did you and your husband go somewhere yesterday?
I'm afraid you bought too many of them, master.
My husband is a politician who doesn’t have any conviction.
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!
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
