More properly Lillu derives from lilium, while Lilliu derives from the Latin lilinus = small lily: in Sardinian lilac. Therefore the pronunciation of the surname is also nasal. In phonetic language we write lill? U for the fall phenomenon of the intervocalic nasal, but the pronunciation is always lilac. This is not a phenomenon of the Sardinian language only, but is also found in the Portuguese, Galician, Gascon, Asturian, Andalusian, French and also in some Sicilian dialects, etc.
