Origin of the Word “Potato”

The English word “potato” traces its roots back to the indigenous Taíno language of the Caribbean, which used the term batata. This was adopted into Spanish as patata, and it merged with the Quechua word papa, used in the Andean regions where the tuber was originally cultivated. The result of this linguistic blending was the English term “potato.”

Interestingly, the German word Kartoffel comes from the Italian tartufolo, which refers to the truffle, for its resemblance to the tuber.

Spanish OriginItalian Influence
batata (Taíno)tartufolo (truffle)
patata (Spanish) 
papa (Quechua) 

The introduction of the potato into the English diet is often attributed to Sir Thomas Herriot in 1586, who brought it from Colombia.
