Two words or phrases are each divided into two pieces; then their second pieces are switched to form two others. Example: ONE = maids, TWO = rapture, THREE = mature, FOUR = rapids. (This would appear in the solutions list as “ma/ids, rap/ture.”)
The solution: ONE = stiletto, TWO = rigor, THREE = stir, FOUR = Rigoletto. (This would appear as “sti/letto, rigo/r.”)
The enumeration of all four parts of a double-cross is given.
When composing or solving a double-cross, be careful not to mix up THREE and FOUR: note that ONE and THREE have the same beginning, as do TWO and FOUR.
In a phonetic double-cross, the parts are rearranged phonetically and not by spelling. For example: ONE = Hall of Fame, TWO = gurneys, THREE = Holofernes, FOUR = game.
In a reversed double-cross, after switching the second pieces of ONE and TWO, you reverse the results to get THREE and FOUR. For example: ONE = red rover, TWO = Erebus, THREE = suborder, FOUR = revere. (This would appear as “red ro/ver, Ere/bus.”)
Based on an idea by Stilicho, the double-cross was introduced by Nightowl at the 1980 convention.
A trans-cross is similar to a double-cross, but the pieces of the word switch AB, CD, AC, BD. For example: ONE = seal, TWO = rely, THREE = sere, FOUR = ally.
The solution: TEAS = Mon-Khmer, EH = oodles, TEE = monkhood, ASH = merles.
The trans-cross was invented by Ucaoimhu.
EXAMPLE: ONE = share, TWO = colt, THREE = sole, FOUR = chart.
The solution: ONE = wine steward, TWO = FDR, THREE = windward, FOUR = fester. (This would appear in the solution list as “win(e ste)ward, F(D)R”.)
A change of heart is similar to a double-cross, except that the pieces that are switched come from the middles of the ONE and TWO rather than the ends. Note that as in a double-cross, ONE and THREE have the same beginnings, as do TWO and FOUR. (See also the heart transplant.)
The change of heart was invented by Lunch Boy and named by Xemu.
In a heart transplant, a letter or series of letters is taken from inside one word and transplanted to another. Example: ONE = clear, TWO = wild, THREE = car, FOUR = willed (transplanting the LE).
The solution: ONE = gerrymander, TWO = caraway, THREE = germander, FOUR = carry away.
The heart transplant was invented by Xemu.
Two words (THREE and FOUR) are joined; then one word (ONE) is dropped out to form another (TWO) from the leftover letters. For example: THREE = reamer, FOUR = itch, ONE = merit, TWO = reach.
The solution: ONE = rondelet, TWO = envied, THREE = environ, FOUR = deleted. (This would appear as “envi(ron, delet)ed.”)
The enumeration of all four parts must be given.
In a progressive dropout, three or more words or phrases are nested (ONE always innermost) to form two others. For example: ONE = ach, TWO = aviator, THREE = latrine, FOUR = La Traviata, FIVE = chorine. (This would appear as “La Tr[aviat(a, ch)or]ine.”)
The dropout, introduced by Nightowl in 1984, is actually identical to one type of the progressive padlock. But the progressive dropout is unique.
