Mezquite
From SUALEX
The word Mezquite (Neltuma spp.; Strombocarpa spp.) (attested in English 1759, Spanish 1591 ([[Creating Haugen, Jason D. 2009. Borrowed borrowings: Nahuatl loan words in English. Lexis: Journal in English Lexicology, (3). |Haugen 2009]])) comes from Nahuatl miskitl <mizquitl>. I have found no cognates for this Nahuatl word in other Uto-Aztecan languages.
