法文
from Old French colpon [piece cut off]

<注釋>A Roman might have had difficulty predicting what would become of the Latin wordcolaphus, which meant .a blow with the fist.. In Old French, a language that developed from Latin,Late Latincolpus, from Latin colaphus, became colp, or modern French coup, with the same sense. Coup has had a rich development in French, gaining numerous senses, participating in numerous phrases,such ascoup d`état (a term that we have borrowed), and giving rise to many derivatives, includingcouper, .to cut; literally, to divide with a blow or stroke.. Couper yielded the word coupon, .a portion that is cut off,. which came to refer to a certificate that was detachable from a principal certificate.The detachable certificate could be exchanged for interest or dividend payments by the holder of the principal certificate.Coupon is first recorded in English in 822 with this sense and then came to apply to forms or tickets, detachable or otherwise,that could be exchanged for various benefits or used to request information.
羅馬人大概很難想像拉丁詞colaphus 意為.拳頭的一擊.所發生的變化。 在由拉丁文發展而來的古法文中，由拉丁詞colaphus 轉變為後期拉丁文中的 colpus ，變為了 colp 或現代法文中的 coup ，意思未變。 Coup 在法文中變化發展很多， 具有了許多意思，組成了許多短語，如coup d`ètat （英文中已借用的單詞），並生成許多派生詞， 包括couper .切；字面上的意思是用一擊或一打使分開。. Couper 又產生了 coupon 一詞，意思是.切掉的一部分.， 並且還用來指可從主要證書中分開的票證。這個可分票證可以由主證書的持有者為得利息或分期付款進行交換。Coupon 有這個意思的最早記錄是在882年， 然後被用來指格式或門票，可分離的或其他樣式，它可以用來交換不同的利益或用來獲取信息
