Pronounced: in-TER-stuhs, noun
Notes: I know a related word, and was close (but not quite right) with the definition
The word virilocal means “relating to the custom of living with the family of the husband”
Background / Comments
As I said yesterday, I had no idea that there was a word for this custom. It comes from Latin vir (man) combined with local.
This is a relatively late word, coming into English in the 1940s
