The story

In Chinese 那 is still the everyday word for "that", but Japan uses it mostly for its sound. 旦那, husband or master, once meant a temple's patron, from the Sanskrit dana, alms-giving; 刹那 is Sanskrit too, and Okinawa's capital is 那覇.

Used in 旦那 (danna, husband/master), 刹那 (setsuna, instant), and 那覇 (naha, Naha, Okinawa's capital)
