Esmeralda, or Esmeraldeño (also called Takame or Atacame), is an extinct language isolate formerly spoken in the coastal region of Ecuador, specifically in the western part of Esmeraldas Province. The only existing data for Atacame was collected by J.M. Pallares in 1877.
It has been proposed that the language is connected to the still-spoken Pumé language of Venezuela. It also has some lexical similarities with the extinct Yurumanguàlanguage, as well with the southern Barbacoan language Tsafiki (especially plant and animal names).
Esmeralda may have had a 5-vowel or 3-vowel system.
Loukotka (1968) lists the following basic vocabulary items.
