Note
A regular superlative, made by adding -est straight onto stiff, with most stiff as the longer alternative. It carries every sense of the base adjective, not only physical rigidity. The stiffest manner is the most formal, and the stiffest penalty is the harshest. The stiffest legs are the sorest after unaccustomed exercise, and the stiffest drink is the most potent. The noun it describes, not the form, tells you which kind of stiffness is meant.
