What is the highest number $n$ of $n$-letter words can you find that share this property? i.e. highest number $n$ that you can find (not found on any other sites).
I will accept the answer with the highest number $n$. So if $n=5$ is the highest out of the answers at a given moment (with a solution different to above), then I will accept the answer with that particular solution. Then, if an answer reveals a solution for $n=6$, I will then accept that since $6>5$.
Good luck, and have fun!
Also, I wonder if one can find a solution where all the given words rhyme, excusing one column that is.
I have used the tag enigmatic-puzzle because I have not officially stated the sharing property of the words shown above, but I am certain it is obvious; I have also used the tag word-problem for clear reasons that disagree with the purpose of using such a tag, however; and I am not fully certain if it is appropriate to include the tag wordplay.
