Not quite. That should be

{ local $,=''; local $\="\n"; print( @splitted_word ); }

or

{ local $"=''; print( "@splitted_word\n" ); }

See $,, $\ and $".

However, using join is less error-prone, more natural, shorter and more versatile (you can use it when you don't want to print).

print( join( '', @splitted_word ), "\n" );
