If the two words PANT and TRY are merged so that the two letter Ts overlap we obtain the word PANTRY. In other words, the parent word PANTRY will split into the offspring PANT and TRY by duplicating the T. Overlaps may be of any length and can occur anywhere in a word except for the first and last letters.
