Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Partly from Gujarati tānkh, cistern (from Sanskrit taḍāgaḥ, pond, perhaps of Dravidian origin) and partly from Portuguese tanque, reservoir (variant of estanque, from estancar, to dam up, from Vulgar Latin *stanticāre; see stanch).]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Portuguese tanque ("tank, liquid container"), originally from Indian vernacular for a large artificial water reservoir, cistern, pool, etc., for example, Gujarati ટાંકી (ṭāṅkī), or Marathi  (take). Compare the Arabic verb استنقع (istanqáʕa, "to become stagnant, to stagnate").
