Abba=Son of the father
Abba = father. Jesus referred to His Father as Abba in His prayer to Him. Jewish children call their fathers Abba.
Thanks, I thought it was part of the Swedish singing group.
No. In Aramaic, "Abba" literally means "father" (it's the cognate of the Hebrew av). It was also used as a man's first name in Second Temple times. "Son" would be bar. The name "Barabas" which appears in the Christian Scriptures means "son of Abba."
