Abba

American Tract Society Bible Dictionary

A Syriac word signifying father. When the Jews came to speak Greek, this word may have been retained from their ancient language, as being easier to pronounce, especially for children, than the Greek pater. It expressed the peculiar tenderness, familiarity, and confidence of the love between parent and child, Mark 14:36; Romans 8:15; Galatians 4:6 .
