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

        public VocabularyWord(string word)
        {

        }

        public override string ToString()
        {

        }

        public override bool Equals(object obj)
        {
            if(word is word)
            {

There are a few issues here:

  • the function still needs to return a bool value when the condition is not met
  • the internal attribute is "Word" (with capital "W") instead of "word"
  • the internal "Word" needs to be compared with the one in the obj
  • the object will need to be cast as a VocabularyWord to access its attribute
  • you'll want to use a separate test or the null coalescing membership operator to avoid errors with null objects
  • the comparison should be for equality ("==") instead of identity ("is")
