You might want to print $1, this will give you a better idea. $1 is
being set to everything in the parentheses, which is everything you
match, and the

Not exactly. It is NOT being treated as a number if that is what you
mean, all of $s is being treated as a string. Specifically \w matches
any "word" character, which is any alphanumeric...so [A-Za-z0-9_].

it's probably easier to use the ucfirst() function:
my $key ="Departure date";
my @result = map { ucfirst } split /\s+/, $key;
$key ="Departure date";
$key =~ s/([\w\w+])/\u$1/;
---> Desired result:
Departure Date
