Jonnathan is a male given name derived from the Hebrew Yehonatan, meaning “Yahweh has given,” and represents an orthographic elaboration of the traditional Jonathan. In Anglo-American usage it is pronounced /ˈdʒɒn.ə.θən/ or /ˈdʒɔn.ə.θən/ and aligns with established English phonetics. U.S. Social Security data over the past fifty years reveal a consistent yet uncommon pattern: annual occurrences peaked at 50 births in 1999 and have stabilized at around ten births per year by 2024, with its rank oscillating between the mid-600s in the early 1970s and the low-900s in recent seasons. This stability underscores Jonnathan’s appeal to parents seeking a name that merges biblical heritage with a distinctive orthographic twist, conveying reliability and thoughtful leadership while maintaining individual character.
