The structural clue

How the ladder gives itself away

BULL → BILL → WILL → WELL → CELL is the structural engine. Every rung ends in LL, so the lower five words can be ordered by changing only the first or second position while the ending stays parked.

  1. StepSolve the middle clues first: FULL for stuffed, BULL for the rising-market animal, BILL for something that may become law, WILL as the opposite of won’t, and WELL for a source of water.
  2. StepArrange them as FULL → BULL → BILL → WILL → WELL, checking that each neighboring pair changes exactly one of the first two letters.
  3. StepPlace FUEL above FULL and CELL below WELL. The endpoints combine as FUEL CELL, the device described by the shared clue.
