The word Tunisia
is derived from Tunis;
a city and capital of modern-day Tunisia.
The present form of the name, with its Latinate suffix
-ia, evolved from French Tunisie.
The French derivative Tunisie was adopted
in some European languages with slight modifications, introducing a distinctive
name to designate the country.
The
name Tunis
can be attributed to different origins. It can be associated with the
Phoenician goddess Tanith (aka
Tunit),
ancient city of Tynes or
to the Berber root ens which means "to lie down".
