Please, explain what %w means

Question

I don't understand "%W" - what does that mean?

string[index].capitalize! unless %w(the and over).include?(string[index])

Your question asks what `%W` means (uppercase "W"), but your example uses `%w` (lowercase "w"). They mean subtly different things, so which do you want to know about? — Jon Cairns, Apr 11 '13 at 09:11

%w creates an array based on the words in it (whitespace separated).

So

%w(the and over)

Will become

["the", "and", "over"]

It is a commonly used method in ruby.

So a portion of your string will be capitalized, unless that portion is either "the", "and" or "over".
