Spanish and Italian form of a Visigothic Germanic name, probably meaning "noble and ready", from the element
adal "noble" combined with
funs "ready". Other theories claim the first element is
hadu or
hild (see
ILDEFONSO), both of which mean "battle". It is possible that two or more names merged into a single form. This was the name of six kings of Portugal and kings of several ancient regions of Spain.
