2,097 PointsCompiler says "override" doesn't work with Equals method...
The compiler accepted an overridden Equals method in the video though, so I'm confused. When I take "override" out, it tells me "not all code paths return a value".
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(VocabularyWord x, VocabularyWord y)
{
if(x == y)
{
return true;
}
}
}
}

The error is unrelated to the override.
Whether it reports it or not, the issue is the same with or without override. Examine your method and you'll notice that the only return statement is within an if conditional block. If the conditional turns out to be false, the method would end without executing any return and thus be unable to satisfy the requirement of returning an item of type bool.
You could fix this by putting another return (presumably with the argument "false") after the conditional block.
But in this case there's an even easier fix, just replace the entire method body with this:
return x == y;
Then, without any conditionals, it will return either true or false based on the comparison.
