The name Marsascala is derived from Marsaskala. Different opinions exist regarding the origin of the name Marsaskala. While it is commonly agreed that Marsa is an Arabic word meaning bay, Skala has given rise to different interpretations. It could have been derived from Sqalli (Sicilian) for Marsaskala was frequented by Sicilian fishermen since Malta is just 60 miles south from Sicily. Maybe it was derived from the Sicilian 'Piccola Cala' meaning little inlet or it was just a reference to some rock-cut steps on the water's edge. (Skala also means a straight flight of steps).
Marsaskala is better known as Wied il-Għajn by the Maltese as the bay and the old small village are flanked by two valleys, through which a spring of fresh water used to flow down into the innermost bay. Wied means valley and Għajn (pronounced ayn) refers to the spring of fresh water. Literally, Wied il-Għajn means Valley of the Spring.
