Cappuccino
from Italian, literally ‘Capuchin’, because its colour resembles that of a Capuchin's habit.
wiktionary
1904, borrowed from Italian cappuccino, from Viennese German Kapuziner(“Capuchin”), due to the similarity of the color of the beverage to the monastic habit of dark brown; [1] compare Franziskaner(“Franciscan”), a contemporary coffee drink with more milk and hence a lighter color, more similar to the latter monks’ habits of light brown. [2] The German term Kapuziner is in turn a loan translation from Italian cappuccino(“Capuchin”) (thus the Italian word for the coffee beverage is a reborrowing), from Italian cappuccio(“hood, cowl”) + -ino(“(diminutive)”), due to the hood of the Capuchin monks’ habits, from Italian cappa(“hood, cowl”) + -uccio(“(diminutive)”) (note two diminutive suffixes), in turn from Late Latin cappa (English cape).
Doublet of Capuchin, also from Italian cappuccino (via Middle French capuchin).
