The "P" of PRNDL (4)
I believe the answer is:
park
'the p of prndl' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for park that I've seen before include "Leave car - recreational area" , "Recreation ground" , "SECOND PART OF 14" , "gear" , "Area for recreation in a city" .)
