The Spanish word 'yautía' comes directly from the Taíno language, which was spoken by the indigenous Taíno people of the Caribbean. In both languages, it refers to a taro-like root vegetable that was an important food crop in Caribbean cuisine. This is one of many words that Spanish borrowed from Taíno languages during the colonial period in the Caribbean, particularly for local plants and foods that were new to European settlers.

As 'yautía' is borrowed directly from Taíno, there aren't any simpler or more common Spanish words that share its etymology. It stands as a unique contribution from the indigenous languages of the Caribbean to Spanish vocabulary.

There aren't any common English words directly related to 'yautía', as it's a borrowing from Taíno. However, English has also borrowed this word in the form 'yautia' (without the accent mark) to refer to the same root vegetable, though it's not commonly used outside of discussions of Caribbean cuisine.
