1. and the following (pages, paragraphs etc.)

• The abbreviation ff. is used in citation to refer to a section for which no final page number can usefully be given. If there is only a single section following, f. may be used instead.
• More properly, it is still used, as originally, to refer to the next page or pages in a citation. As such, Hornblower 258 f. would refer to pages 258–259, whereas 258 ff. would refer to an undetermined number of pages following page 258.

ff. (indeclinable)

1. (of pages) Abbreviation of folgende(n) pl (“following”, “subsequent”); akin to English ff., et seqq.. (The word fortfolgend has been coined as a folk-etymological explanation of this abbreviation and is not commonly encountered in other use than this fanciful explanation, which is in fact a backronym.)
