Answer:
Abigal is an Italian equivalent of the English name Abigail.
Specifically, both the English and Italian names are feminine proper nouns. They both derive from an ancient Hebrew name which may be written אֲבִיגָיִל or אֲבִיגַיִל. The original meaning is "her father's joy" or "fountain of joy."
The pronunciation will be "ah-bee-gahl" in Italian.
