levir
Levir is Latin for a husband's brother, a woman's brother-in-law through her husband.
Levir is a precise Latin word for the brother of a woman's husband. Roman legal writers defined it that way, and genealogical word lists keep the same meaning.
It is rare in registers, but when it appears it is valuable: a witness or godparent called levir links two brothers through the wife. The Latin for a husband's sister is glos.
