The "context" means the context that the function is called in -- whether the values of the function will be used in list or scalar context.
use strict;
use warnings;
sub what_do_you_want {
print wantarray ? "list\n" : "scalar\n";
}
my @list = what_do_you_want(); # prints "list"
my $scalar = what_do_you_want() # prints "scalar"
