fivefold
means five times. For instance, if an article has 1000 bytes of prose (not the whole article, see the "prose" entry), it must be expanded to 5000 bytes of prose (not the whole article) to be considered new, and thus eligible for Did you know.

hook
An example of a hook is "... that Jon Olav Alstad was elected to the Norwegian Parliament at the age of 25?" The Did you know section on the Main Page contains about eight hooks, usually starting with "... that" and ending with "?".

From there, an administrator will eventually move each preparation area page into one of the queues, after which DYKADMINBOT will move it to the Main Page. See "update".

prose
At Did you know, only characters of "prose" are counted when measuring the length of an article, whether it's to meet the 1,500 character minimum, or to calculate whether an article has been expanded fivefold. Characters of prose are counted by the User:Shubinator/DYKcheck script, which excludes infoboxes, categories, references, lists, tables, block quotes, headers, images and captions, the "See also" section if any, Table of Contents, edit buttons, "citation needed" and similar superscripted text, and reference link numbers like [6].
