No lease for aeroplane's parking space at the airport (5)
I believe the answer is:
apron
'no lease' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'for aeroplane's parking space at the airport' is the wordplay.
I cannot really understand how this works, but
'for' could be 'pro' (I've seen this before) and 'pro' is found within the answer.
The remaining letters 'an' 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 apron that I've seen before include "Kitchen garment or aerodrome strip" , "Airport area for manoeuvring and loading planes" , "Aircraft parking area" , "item of protective clothing" , "Area for aircraft not in use" .)
