So it seems as 'lingua franca' had its variants ...
https://en.wikipedia.org/wiki/Lingua_franca
"Portuguese served as lingua franca in the Portuguese Empire, Africa, South America and Asia in the 15th and 16th centuries. When the Portuguese started exploring the seas of Africa, America, Asia and Oceania, they tried to communicate with the natives by mixing a Portuguese-influenced version of lingua franca with the local languages. When Dutch, English or French ships came to compete with the Portuguese, the crews tried to learn this "broken Portuguese". Through a process of change the lingua franca and Portuguese lexicon was replaced with the languages of the people in contact."
