Hey there Fabiola Barrientos ,

You'll want to use the override modifier for this method that has an expected return type of int.

Hope this helps!

Ive already tried that, but when I do I get the message: "VocabularyWord.cs(32,35): error CS0428: Cannot convert method group GetHashCode' to non-delegate typeint'. Consider using parentheses to invoke the method" Whenever i try to use "(int)" on "VocabularyWord" I get the same message, and when I use it on "GetHashCode()" I get the message: "VocabularyWord.cs(32,34): error CS1001: Unexpected symbol `(', expecting identifier"

Here is the code 

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

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

        public override string ToString()
        {
            return Word;
        }

        public override bool Equals(object obj)
        {
            if(!(obj is VocabularyWord))
            {
                return false;
            }

            var that = obj as VocabularyWord;

            return this.Word.Equals(that.Word);
        }

        public override int GetHashCode()
        {
            return VocabularyWord.GetHashCode();
        }
    }
}

You're very close, but "VocabularyWord" is the name of the class itself. The name of the attribute variable where the string is stored is just "Word":

            return Word.GetHashCode();
