I like to play around with words, not with their meanings but with their physical properties. The result is the puzzles that I post here from time to time. I recently set myself the challenge of finding a word in which the first letter can be changed to form another valid English word, then the second letter and so on, at each stage forming a valid word.
This is how this process might work for a four-letter word:
CORE…PORE…PARE…PALE…PALM
However, finding a solution involving five-letter words is much harder. To date, I’ve found five solutions, although I imagine that there are many more. Can you find one?
Incidentally, I’ve tried to find a solution for six-letter words, so far without success. Can you?
