The Origin of Tuani
Tuani comes from Malespín Spanish. In the 1840's General Francisco Malespín started sacking nearby Nicaraguan towns. Leading all the way to Leon Nicaragua.
The Salvadorian military adopted speaking in code later called Malespín.
The code works by switching “a” for “e,” “i” for “o,” “b” for “t,” “f” for “g” and “p” for “m,” and vice versa.
Take the word-bueno
Language migrated southward, and with time El Salvador, Nicaragua, Costa Rica and Panama use some derivative of Malespín.
