And you can use
Elsa,
Elisa,
Elise,
Lisa etc. as a full name so why not Lilibeth? Lilibeth sounds like a full name and could also be seen as a combination of
Lily and
Beth. Why are people so afraid of a nn as a full name?
Elizabeth is a mouthful with all 4 syllables; Lilibeth is better imo.
Lisbeth is another short form of
Elisabeth and used in Sweden. And nobody would say "use the full name
Elisabeth instead".
