✔ 最佳答案
PS是一個拉丁語
Post scriptum
簡寫,
意為「完筆後附加」,
一般是在寫信簽名後附加上的內容。
Perhaps the most common postscript found in love letters is "P.S. I love you!" This title was given to at least two popular songs, one by Rosemary Clooney and one by The Beatles.
P.S. is sometimes used as a purely stylistic touch, when it isn't really necessary.
P.P.S. is a "Post-postscript" and allows the letter writer to add even more thoughts after the first postscript. To continue, a third postscript would be a P.P.P.S. and so on, although these additions are rarely used in practice.
