From what language does the word "mango" come from?

mango — this sweetly fragrant, succulent tropical fruit (Mangifera indica) is called mân in Tamil; the Tamil word for 'unripe fruit' is kây, so mân-kây became mangga in Malay and then mango in English via Portuguese. Why do we call the mango after its unripe version? Maybe because of commerce: fruit merchants shipped green mangoes because of their longer shelf life, to ripen later, and the non-Tamil merchants were used to hearing "mân-kây", so that became the basis of their word for them. When Tamilians eat mangoes, they call them mâm-palam, using the word for ripe fruit.

The name "mango" is derived from the Tamil word "mangay" or "man-gay." When the Portuguese traders settled in Western India, they adopted the name as "manga."
