with horizontal symmetry?
with vertical symmetry?
with 180 degrees rotation symmetry?

What are the LONGEST words in each category? (Common words are preferred.)

Iain: "'Words with symmetry' cannot mean 'words with symmetrical letters'. That's like saying that a picture is symmetrical if it can be broken up into pieces such that each piece is symmetrical. I don't mean to be rude, but your argument is a little thin."

Cool, Iain. I am never offended when someone calls me thin. I could be a stickler and point out that we say that America is "a nation with civic pride" because it is made up of people who have civic pride. But I will not make that argument. In the immortal words of George W. Bush, "One of the common denominators I have found is that expectations rise above what is expected. Never again in the halls of Washington,D.C. do I want to have to make explanations that I can't explain. I hope we get to the bottom of the answer. I am a person who recognizes the fallacy of humans. I don't do nuance. If the terriers and bariffs are torn down, this economy will grow."
