This isn't really what I would call sorting.
You could either squeeze and transliterate all non-alphabetic sequences into newlines
tr -sc '[:alpha:]' '[\n*]' < PDF or (at least with GNU grep) match and output sequences of word characters (alpha, decimal digits and underscore), one per line using the -o option
grep -o '\w*' PDF
