Mosquito, the diminutive of mosca, was borrowed into English (first recorded around 1583) with the same sense "mosquito" that it had in Spanish and Portuguese. The Romance language French was the source of our wordmusket (first recorded around 1587), which came from Frenchmousquet, but this word entered French from yet another Romance language, Italian.From the descendant of Latinmusca, Italian mosca, was formed the diminutive moschetta with the senses "bolt for a catapult" and "small artillery piece.” Frommoschetta came moschetto, "musket,” the source of Frenchmousquet. The use ofmoschetta, literally "little fly,” to mean "bolt from a crossbow"can be ascribed to the factthat both bolt and insect fly, buzz, and sting.苍蝇将永远不会成为受人欢迎的动物，尽管或也许正因为它们无处不在。苍蝇影响我们生活的两个例子可在两个单词mosquito 和 musket 词源中找到， 两者都可追溯到musca， 拉丁文中是“苍蝇”的意思。这个拉丁文单词在西班牙语、葡萄牙语和其他由拉丁文演变而来的语言中变为mosca 。 Mosca 的小词 mosquito 被借入英语中（大约于1583年首次出现）跟它在西班牙语和葡萄牙语中一样，都表示“蚊子”。 从拉丁文演变来的法语是单词musket （大约在1587年首次出现）的词源， 这个词来自一个法语词mousquet ， 但这一词仍然是从另一个由拉丁语演变而来的意大利语中借入法语的。起源于拉丁语musca 的意大利单词 mosca 形成了一个小词 moschetta ， 意思是“弹弓上使用的螺钉”和“小炮弹”。 从moschetta 中产生了 moschetto 意为“火枪”， 是法语词mousquet 的词源。 moschetta 的字面意思是指“小苍蝇”， 用来比喻“弩上的弓箭”，这可以归因于一个事实，那就是弓箭和苍蝇都会飞，并且都能发出嗡嗡声而且会刺伤人〔setscrew〕A screw, often without a head, used to hold two parts together.固定螺钉：连接两部分的螺钉，通常无头 |
