A specified letter is changed to make a new word or phrase. For example (a third-letter change): ONE = pastry, TWO = pantry.
The solution: A = wither, B = either. (The solution would appear as “w/e-ither.”)
Letter changes can have more than two parts. For example: ONE = boast, TWO = beast, THREE = blast.
If the last letter is being changed, the flat is called a last-letter change. For example, ONE = molts, TWO = molto is called a last-letter, instead of a fifth-letter, change.
In a reversed letter change, a letter is changed in a word or phrase and the result is then reversed to make another. For example (reversed second-letter change): ONE = twanger, TWO = regnant.
In the Brookline letter-change, a word or phrase changes each one of its letters in turn to make others. Example: BASE = rice, ONE = nice, TWO = race, THREE = rile, FOUR = rich.
The solution: BASEWORD = chase, A = phase, B = cease, C = chose, D = chafe, E = chasm.
The Brookline letter-change was introduced by Newrow (from Brookline MA) in 1991.
See also repeated-letter change.
A word or phrase becomes another when one letter is changed to another letter wherever it appears (the letter must appear at least twice). For example: ONE = monocle, TWO = manacle.
The solution: PRIMAL = crochet, FINAL = prophet.
A repeated-letter change may have more than two parts. For example: ONE = skunk, TWO = stunt, THREE = sauna. In this example, the second and fifth letters are changed in ONE to make TWO; the same positions must have changed letters to form all other parts.
As is true of similar types (like the spoonergram, transposal, reversal, and letter change), the repeated-letter change must work in both directions -- that is, be reversible. For example, puffy cannot be changed to puppy, because reversing the change would produce fuffy, not the original puffy.
The repeated-letter change was introduced by WILLz in 1980.
One sound is changed in a word or phrase to make another. Example: ONE = tungsten, TWO = tonguester (a last-sound change).
The solution: ONE = legroom, TWO = legume.
See also the discussion of what constitutes a single sound under phonetic flats.
A word or phrase (ONE) contains a shorter one (TWO) within it; when this is removed and another (THREE) is substituted, a new word or phrase is formed (FOUR). For example: ONE = wander, TWO = and, THREE = is, FOUR = wiser. To save space on the solution page, this may appear as “w-and/is-er.” Another example: ONE = Pandora, TWO = and/or, THREE = ark, FOUR = parka. The enumeration of all parts is given.
The solution: PRIMAL = consultant, SECOND = sultan, THIRD = sign-men, FOURTH = consignment.
If the smaller parts to be substituted are at the beginnings of the words, the puzzle is an initial-word substitution. For example: ONE = pungent, TWO = pun, THREE = deter, FOUR = detergent.
If the smaller parts to be substituted are at the ends of the words, the puzzle is a final-word substitution. For example: ONE = Cleveland, TWO = land, THREE = rest, FOUR = cleverest.
In an extended word-substitution, the shorter word is replaced more than once to form new words. For example: ONE = list, TWO = is, THREE = en, FOUR = lent, FIVE = of, SIX = loft.
The word substitution was invented by Alf.
