Of course. You cannot have $3 as a lvalue (read: You cannot
change its value).

Don't make it more complicated than it is. :-)
% wn foot -over | grep "Overview" | awk \
'{ printf("%s %s\n", $4, gsub("noun", "n.", $3)); }'
And the more I think about it, the more I believe there are
much easier ways to do this. But I'm sure the magic of how it
works just opened up to you.
Sidenote: I wouldn't consider myself as an AWK expert allthough I
did abuse AWK lately to implement a stastistical evaluation program
for blood sugar data into a PDF file with diagrams a CVS file,
involving gnuplot and \LaTeX{}. =^_^=
