dog-leg, dogleg, or dog leg? has one well-received and currently accepted answer but was quickly closed for lack of research. It was only my second question here, over three years ago now.
I'd accepted the answer after the question was closed, the possibility of other answers having been blocked by the closure.
To the comment "What do dictionaries say" I'd replied, but I didn't realize that responding quickly in comments was insufficient and that I was required to report what "dictionaries say" in the question itself to prevent closing.
Of course now if I follow the close reason instructions "Please include the research you’ve done..." it would be awkward because it could appear to be copying information from an answer back into a question, or changing the question after an answer was posted.
However keeping the question closed blocks the entire community from posting any additional answers. While closing may have seemed punitive at the time, or a way to encourage editing the question, it is now having the effect of preventing answers.
I'd like to allow for the possibility of additional answers, but I'm uncertain how I can modify the question in such a way as to still be fair to the existing answer. How might I proceed?
Granted someone may argue that the existing answer is "perfect" and no additional answers are possible, but we don't know that yet. Reopening the question offers an opportunity to see if a better or at least supplementary answer is possible.
