Last week we dealt with the monks - today's explanation follows on directly from that.
It's supposed to be about the hood and in the beginning it was mainly worn by monks and women. As is often the case, the origin of the word was Latin. There it was still called “caputium” and the meaning was “an enveloping headgear”, more precisely: “the tip of the cap hanging on the cap to be thrown over the head”.
In French it became “capuce” and in Italian “cappuccio” – incidentally related to “cappuccino”. It got its name because of its cream topping, which – mixed with the mocha – is reminiscent of the habit of a Capuchin monk.
