multi method words(Str:D $input: $limit = Inf --> Positional)

passing the $limit parameter in with 3, limits the number of words

"a b c d".words(2);
(a b)
Passing a $limit of 2, limits the words returned to 2.
If you *don't* set $limit at all, it gets set to its default, Inf, or
all the words. It just never stops because there is no limit.
"a b c d".words();
(a b c d)
The () are optional since you aren't passing in any parameters, so you
can also just say
"a b c d".words;
(a b c d)
You can store that in a variable
my @x = "a b c d".words;
Once you've got that in a variable, as described in detail on the page
about Positional, you can access parts of it with the [] operator, for
example, the word in the '2' position (the third word counting from 0) is
@x[2]
c
What looks a little weird is that you don't need @x at all. You can
just call the [] operator directly on the return value from words
"a b c d".words()[2]
c
and of course, you can omit the () since you aren't passing in
parameters, so this is the same thing
"a b c d".words[2]
c

Perfect! Thank you!
