Answer 2

This question has been asked three times before on Yahoo dating back to over a year ago. The three askers were all different. All answers we chosen by voters, but none were correct. I googled every possible question to get the right answer. I got no where. I even looked up every four letter word in the English language but none seemed to answer all four catagories. Anyone who has tried to answer has also failed. So could you please give us a hint? Maybe the first letter? Is it a common word? Do you even know the answer?
It is very aggrevating to not get the answer from the asker for any puzzle and not just yours. If we no one gets it will you please share? Thanks! Where did you get this question from? Is there really an answer?
