Unclear etymology, from à- + gbọn, likely a Yoruba coinage as the words for coconut in Central Yoruba or related languages like Itsekiri, Igala, Edo, Igbo, Nupe, are not related from this (most come from a Portuguese root). Other languages that don't have borrowings from Portuguese usually use a variation or compounding with a word for the oil palm tree, which is similar to the coconut. This may also suggest that Western Yoruba speakers did not receive coconuts from the Portuguese, and instead may have gotten it from another source. Compare with Ifè àgbã. *Unlikely, but possibly from à- (“nominalizing prefix”) + gbọ̀n (“to shake”)?
