alpaca (n.)

Andean mammal valued for its wool, 1792, from Spanish alpaca, probably from Aymara allpaca, related to Quechua (Inca) p'ake "yellowish-red." The al- is perhaps from influence of the Arabic definite article being a common element in Spanish words (compare almond). Attested in English from c. 1600 in the form pacos.
