Change of heart
Two words or phrases are each divided into three pieces; then their middle pieces are switched to form two others. Example: ONE = share, TWO = colt, THREE = sole, FOUR = chart. (This would appear in the solution list as “s(har)e, c(ol)t.) Another example: ONE = wine steward, TWO = FDR, THREE = windward, FOUR = fester (“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.)
In a cross my heart, the switched pieces come from the middles of ONE and THREE, but the ends of TWO and FOUR. Example: jeopardy, lump, jumpy, leopard.
The change of heart was invented by Lunch and named by Xemu. The cross my heart was invented by A. Chemem.
