Admire oneself for parking about space (5)
I believe the answer is:
preen
'admire oneself' is the definition.
(I've seen this in another clue)
'for parking about space' is the wordplay.
'for parking' becomes 'p' (I can't justify this - if you can you should believe this answer much more).
'about' becomes 're' (regarding).
'space' becomes 'en' (in printing, a space as wide as a letter 'n').
'p'+'re'+'en'='PREEN'
Can you help me to learn more?
(Other definitions for preen that I've seen before include "Perfect one's appearance" , "Array (oneself) carefully" , "Arrange feathers" , "Titivate oneself" , "Clean with the beak" .)
