A note added after the main body of a letter or document. Often used in formal or personal correspondence.
I added a postscript at the end of the letter.
The postscript noted the date and time of the next meeting.
Standard modern spelling using the hiragana って for the okurigana portion.
Abbreviated form of 追而書き, omitting the final き; rare and literary.
Uses the ateji 而 for って; encountered in older or formal writing.
Compound of 追って (adverbial form of 追う, 'to follow') + 書き (continuative form of 書く, 'to write'), literally 'writing that follows'. The kanji 而 is an ateji for the reading って.
