Froilán is a derivative (with the declination in
-an(i) of the Germanic names ending in
-a) of
Froila, a Visigothic name coming very probably from the Germanic root
frau, "master", and the diminutive ending
-ila, very usual in Visigothic names (
Favila, Ulfila...).
The pronunciation of Froilán is [froj'lan](froy-LAHN).
The Spanish Royal couple's grandson is in fact named Felipe (nicknamed Pipe by his family) but is known popularly as Froilán, his third baptismal name: he was baptized Felipe Juan Froilán de Todos los Santos, after his uncle (Prince Felipe), his grandfather (king Juan Carlos) and his great-grandfather (the count of Barcelona, Don Juan) and after the saint patron of Lugo (saint Froilan), because his mother is the Duchess of Lugo. As Froilán is a very unusual name (especially among young people), the media began to refer to him as Froilán instead of Felipe or Pipe.
