Wamo–Chapakúra is a proposed connection between the largely extinct Chapacuran language family and the otherwise unclassified language Wamo (or Guamo).
Kaufman (1990) finds the connection convincing.
Below is a comparison of Guamo (1778 word list[1]) with Proto-Chapacuran reconstructions from Angenot (1997).
[2] Similar forms include Proto-Chapacuran *ʔakom and Guamo cum ([kum]) 'water'.
