Søs

Not an SOS but a short form of the Danish word for sister — søster — meaning this anme could be compared to the English "Sis". It entered the Top 50 in Denmark in a recent year, with nearly 140 babies receiving it as their given name.

Actress Søs Egelind and singer Søs Fenger have used Søs as a stage name which may have helped popularize it.

Pronounced SURS.
