What I want it to do is join the first through the ultimate words in s.
If you don't know what $#s means, then maybe you could ask? If you don't
know what (1..$#s) means, then maybe you could ask? Using code fragments
that you picked up somewhere without knowing their meaning an throwing
them together rarely produces useful code.

$@s is the highest index in the array @s, i.e. a number.
(1..$#s) is the list of numbers from 1 to the highest index of @s.
Nowhere does it relate to the content of @s.

What you want is maybe @s[1..$#s]
which is a slice of the array @s, containing the elements from index 1
to the highest index. However I would probably use shift() instead to
remove the first element from an array.
