European driver, inexperienced adult, double parking (4)
I believe the answer is:
lapp
'european' is the definition.
(Lapp is an example)
'driver inexperienced adult double parking' is the wordplay.
I cannot quite see how this works, but
'adult' could be 'a' (abbreviation) and 'a' is present in the answer.
'parking' could be 'p' (abbreviation on road signs) and 'p' is located in the answer.
The remaining letters 'lp' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lapp that I've seen before include "A North Scandinavian" , "Finno-Ugric language?" , "Native of N. Scandinavia" , "Someone from Father Christmas's country?" , "Northern Scandinavian native" .)
