Try this,

Code:
$ awk '{ for(i=$NF;(NF-i)<NF;i--) { printf "%s%s",$(NF-i),FS } printf RS }'  input_file

I haven't tested all the corner cases.

polish

POLISH(5)							      Debian								 POLISH(5)

NAME

       polish - a list of Polish words

DESCRIPTION

       /usr/share/dict/polish is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       /etc/dictionaries-common/words  is  a  symbolic	link  to  a  /usr/share/dict/<language> file.  /usr/share/dict/words is a symbolic link to
       /etc/dictionaries-common/words,	and  is  the  name  by	which  other   software   should   refer   to	the   system   word   list.    See
       select-default-wordlist(8) for more information.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french
       and /usr/share/dict/danish contain respectively lists of French and Danish words if they exist.	Such lists should be coded using the UTF-8
       character set encoding.

SEE ALSO

       ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

       The  system word list used to be /usr/dict/words.  For compatibility, software should check that location if /usr/share/dict/words does not
       exist.

AUTHOR

       Word lists are collected and maintained by various authors.
