COPY goes to COY if you 'take the p'. Match each clue up with its mate that differs by removing the letter P. Then construct a Morse message using the Morse code you have constructed by pairing up the clues.

Some answers to the clues are:
Topography = TERRAIN
Depends = RELIES
Erase = DELETE
Compels = FORCES
Threat at sea = PIRATE
Nip, squeeze = PINCH
Stuffed, like a jacket = PADDED
Neuters = SPAYS
