Add a ToString method to the VocabularyWord class that returns the word. Don't understand the question

I don't understand what has to be build?

VocabularyWord.cs 
using System;
namespace Treehouse.CodeChallenges
{
    class VocabularyWord
    {
        public string Word { get; private set; }

        public VocabularyWord(string word)
        {
            Word = word;
        }
        public string VocabularyWordToString(string word)
        {
            Word = word.ToString();
            return Word;
        }
    }
}

using System;
namespace Treehouse.CodeChallenges
{
    class VocabularyWord
    {
        public string Word { get; private set; }

        public VocabularyWord(string word)
        {
            Word = word;
        }
        public string ToString()
        {
            return Word;
        }
    }
}

So you can do 

VocabularyWord word = new VocabularyWord("House");
string vocab = word.ToString()   //Will return "House" so vocab = "House"

The ToString() method is usually overidden in your classes since it is defined in the Object class.

So a correct way to define a ToString() method would be

public override string ToString()
{
    return Word;
}

I don't really get this.. It already returns a string type value. Why do we need to override it??

The syntax on the MSDN page is:

public virtual string ToString()

Oke i understand the function of override, but why override string?

I mean the function of this to string method.

You are not overriding string. string is just the return type of the ToString() method. You are overriding ToString() of the Object class.
