Ellianna is an elaborated spelling of Eliana, which is usually traced to the Hebrew Eliyana, "my God has answered", though it is sometimes linked to the Roman family name Aelius and the Greek helios, "sun". To American ears it also reads as a blend of the favorites Ellie and Anna. Ellianna was number 1046 in 2015, entered the top 1000 in 2016, peaked at 618 in 2023 and ranks 643 among US girls' names in 2025.
