Uiara
Pronounced oo-ee-AH-rah
Meaning: lady of the water
History & Origin
Uiara (also spelled Iara or Yara) is an Old Tupi compound: y (water) + îara (lord; lady) = 'lady of the water.' The figure originates as Ipupiara, a dangerous aquatic being described in Portuguese colonial records from the 1560s. Over time the monster became feminine and seductive, and under the influence of European siren mythology introduced by colonizers, transformed into a mermaid-like spirit who lures travelers into rivers. The pre-European figure had dark skin and black hair; the blonde, green-eyed image appeared in 19th-century Romantic poetry by Gonçalves Dias. Today Iara and Yara are popular given names across Brazil. The etymological form Uiara is closest to the Old Tupi source.
