sionnach This glimpse into how my mind functioned "about 4 years ago" is terrifying to me now! May 5, 2011

uselessness Nothing wrong with insanity. :-)
How about grove? I like the contrast between the place of death and the place of life. Mar 10, 2007
sionnach Hmmm. Interesting. deadliness was what I had in mind, but headlines works just as well, if not better. I wasn't requiring antonyms, just that the two words be 'far apart' in meaning. This is obviously not a well-defined idea. Depending on your point of view, that makes things more interesting, by opening up the possibilities, or less so, because it might open up too many possibilities.
I'm going to add both headlines and deadliness. Let's try one more starter word.
grave
On edit; I think that what will make this list interesting is to find starter words that afford the greatest number of options.
Well, interesting to me, anyway. Other folks probably think I'm insane. Mar 10, 2007
oroboros I can imagine deadlines being dreadlines, but I'll bet that's not what's wanted here.
deadliness? Mar 10, 2007
uselessness Are word 1 and word 2 supposed to be antonyms of one another? Or just unreleated? If I'm understanding the rules right, I guess headlines...? Mar 10, 2007
sionnach To make things interesting, I will start out by listing only one of the pair I have in mind, so that folks can guess the other. To be clear: "differing by one letter" means that word 1 can be changed to word 2 in one of three ways - adding a letter, deleting an existing letter, changing an existing letter. Swapping the position of two existing letters (e.g. CRAVE/CARVE) does not count. Mar 10, 2007
