the output that i wrote in the post is an error

But you haven't shown what the correct output should be so we can only guess what you are trying to do. Here's my guess, matching a combination of words from FIC with lines in FICC

#!/usr/bin/perl
use strict;

my @FIC = ();
#open FIC,'<','fic.txt' or die "$!";
#while (my $line = <FIC>){
#  next unless $line =~ /\S/;
#  my @words = split /\s+/,$line;
#  push @FIC,[ @words ];
#}
#close FIC;
@FIC = (
  [ qw(chirac prime paris)],
  [ qw(chirac prime jacques) ],
  [ qw(chirac prime president) ], 
  [ qw(chirac paris france) ],
  [ qw(chirac paris french) ],
);

my $u=0;
open FICC,'<','ficc.txt' or die "$!";
#open OUT, '>','output.txt' or die "$!";
while (my $line = <FICC>){
  ++$u;
  next unless $line =~ /\S/; # skip blank lines
  for my $ar (@FIC){
    my @matched = grep $line=~/$_/,@$ar;
    if (@matched == @$ar){
      print "$u: $line matched all words : @matched\n\n";
      #print OUT "$u: $line matched all words : @matched\n\n";
      last;
    }
  }
}
close FICC;
#close OUT
