The name Ianeira is derived from the Greek Ἰάν (Ian), a variant of Ἴων (Ion), meaning 'Ionian'. The Ionians were one of the major tribes of ancient Greece. The name Ianeira, meaning 'lady of the Ionians', was borne by several characters in Greek mythology, including one of the Nereids and one of the Oceanids. These mythological figures were associated with the sea and water, reflecting the name's deep connection to Greek cultural and natural elements.
