Kate spilled black ink on her white dress.

    Kate spilled black ink on her white dress. Can you turn black into white by changing one letter at a time? Each step must create a valid word in the English language. Kate made the change in 8 steps. Can you do as well ... or better?

    Yes
    the Webster's Third New International Dictionary
    that happens to be here does in fact
    have PLACK as an English word
    so that does work

    Here is one with seven transitions
    that uses valid English words
    (from the fat Webster's, which
    doesnt allow BRITE as an alt.
    spelling of bright)

    0.BLACK
    1.BRACK
    2.BRICK
    3.TRICK
    4.TRICE
    5.TRITE
    6.WRITE
    7.WHITE


    according to Webster's
    brack is salty or alkaline water
    I guess that is where the adjective "brackish"
    comes from

    Did you actually see BRACK in a dictionary, or is that just a bluff? It's not in any dictionary I can find (although I haven't looked in the HUGE Webster's yet).

    Are you sure you didn't see "brak", which I find referenced several places as a Dutch word meaning salty and given as the derivation of the English "brackish".
