ruby capitalize doesnt work for the first word of the title

Question

the code below is to capitalize all words except for 'littleWords' and the first word of the title. (even if it belongs to the littleWords, the first word should be capitalized.)

 def titleize (word)
    littleWords = ["and", "the", "over", "or"]

    words = Array.new
    words = word.split(" ")
    titleWords = Array.new

    words.each {|word, index| 
        if index == 0
            word = word.capitalize
        else
            unless littleWords.include?(word)
                word = word.capitalize
            end
        end
        titleWords << word
    }
    return titleWords.join(" ")
end 

and test code is the below.

it "does capitalize 'little words' at the start of a title" do
    expect(titleize("the bridge over the river chao praya")).to eq("The Bridge over         the River chao praya")
  end

but it keeps to capitalize the first 'the' as just 'the' instead of 'The'. I wonder which part of my code is wrong. help me... TT

You should use each_with_index instead of each to get the index
