cognate
koh-NYAH-tah
Cognata refers to your spouse's sister or your sibling's wife. The word shares its Latin root with 'cognate' (words of the same origin). False friend alert: 'cognate' in linguistics ≠ 'cognata' in Italian.
La mia cognata abita nello stesso palazzo di noi.

Mia cognata e io andiamo spesso a fare shopping insieme.
My sister-in-law and I often go shopping together.
