The Spanish word 'moringa' comes from the Tamil word 'murungai', which refers to the drumstick tree (Moringa oleifera). This tree, native to parts of India and South Asia, was known in Tamil Nadu where its name was borrowed into other languages as the tree spread globally. The shift from Tamil 'murungai' to Spanish 'moringa' involved a slight modification in pronunciation to better fit Spanish phonology.

There aren't many common Spanish words directly related to 'moringa' since it's a relatively recent borrowing from Tamil. The word stands somewhat isolated in Spanish vocabulary, being specifically used to name this nutritious tree and its products.

The English word 'moringa' is also borrowed from the same Tamil source 'murungai'. Both English and Spanish use essentially the same form of the word to refer to this tree, which has gained popularity globally due to its nutritional properties. While the word might seem unfamiliar to many English speakers, it's becoming more common as the plant gains recognition as a 'superfood'.
