Very fascinating!!

Quoted: Palenquero was strongly influenced by the Kikongo language of Congo and Angola, and by Portuguese, the language of traders who brought African slaves to Cartagena in the 17th century. Kikongo-derived words like ngombe (cattle) and ngubá (peanut) remain in use here today.

Advocates for keeping Palenquero alive face an uphill struggle. The isolation that once shielded the language from the outside world has come to an end. Once three days by mule to the coast, the journey to Cartagena now takes two hours by bus on a bumpy dirt road.
