Esmeralda–Yaruro or Takame–Jarúroan is a proposed connection between two unclassified languages or language isolates of Venezuela and Ecuador respectively: Pumé, with 6,000 speakers, and the extinct Esmeralda. The proposal was first advanced in 1902. They would be only distantly related, but Kaufman (1990) finds the connection convincing, and Campbell (2012) believes the connection is promising.
