I would like to get the first word from each row of my @AoA[][] and push it into the array @kmers. Can anybody help me get there? This is what I've done so far. Thanks in advance everybody! 

my(@kmers);
my($x) = 0;
my($y) = 0;
for ($x=0, $x<7, $x++){                
    for ($y=0, $y<$AoA[$x], $y++){
        my($firstword) = '';
        $firstword = $AoA[$x][$y] =~ /^(\w+)/;
        push @kmers, $firstword;
        print $firstword."\n";        
        }
    }
