Add look_up method instead of parsing in initialize
user
```ruby
require 'nokogiri'
require 'open-uri'

module Oxford
  module Learners
    module Dictionaries
      class English
        attr_reader :definition, :url, :word, :page

        def initialize word
          @word = word
          @url = "http://www.oxfordlearnersdictionaries.com/definition/english/#{word}"
          @definition = Hash.new
        end

        def look_up
          @page = Nokogiri::HTML(open(@url))
          parse
        end

        private
        def parse
          if @page.css(".n-g").count > 0
            multiple_definitions
          else
