The
Supanecan or
Tlapanecan languages are
Tlapanec (Me'phaa) of
Guerrero and the extinct
Subtiaba of
Nicaragua. The family was recognized in 1925 by
Edward Sapir, who linked them to his
Hokan proposal. However, they are the most recently recognized members of the Oto-Manguean language family, the relationship having been demonstrated in 1977 by Jorge Suárez.
