Delight from learner after parking with no trouble (6)
I believe the answer is:
please
'delight' is the definition.
(I know that delight can be written as please)
'learner after parking with no trouble' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'after' is a charade indicator (letters next to each other).
'parking' becomes 'p' (abbreviation on road signs).
'with' means one lot of letters go next to another.
'no trouble' becomes 'ease' (I've seen this in another clue).
'l' after 'p' is 'pl'.
'pl'+'ease'='PLEASE'
'from' is the link.
(Other definitions for please that I've seen before include "Asleep (anag)" , "(Word used in) asking or accepting politely" , "Cause (someone) to feel satisfied" , "Polite addition to a request" , "Delight, satisfy" .)
