Heart transplant
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). (This would appear in the solution list as “c(le)ar, wil|d”.) Another example: ger(ry)mander, car|away. (See also change of heart.)
The heart transplant was invented by Xemu and introduced in June 1997.
