You should print $_ instead

Or, just add the /r modifier to the substitution:

#! perl use v5.14; use warnings; use strict; my %words = (word => 1, word2 => 1, word3 => 1); my ($temp, $temp1) = qw(WORD2 word2); $_ = 'here is word2'; say s/$temp1/$words{$temp1} ? "$temp " : "[$temp] "/er;

Output:

13:14 >perl 515_SoPW.pl here is WORD2 13:15 >

From s/PATTERN/REPLACEMENT/msixpodualgcer in Regexp Quote Like Operators:

r Return substitution and leave the original string untouched.

Hope that helps,

    It should be made clear that the  s///r regex switch is only available with Perl versions 5.14 and above.
