Awaiting customers in park, German philosopher takes air around ten. (4,4)
I believe the answer is:
taxi rank
'awaiting customers in park german' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'philosopher takes air around ten' is the wordplay.
'philosopher' becomes 'tank' (I can't justify this - if you can you should give a lot more credence to this answer).
'takes' indicates putting letters inside.
'around' indicates putting letters inside.
'ten' becomes 'X' (Roman numeral).
'tank' going around 'air' is 'tairank'.
'tairank' enclosing 'x' is 'TAXI RANK'.
Can you help me to learn more?
(Other definitions for taxi rank that I've seen before include "Parking place for cabs" , "Line of cars waiting to to hired" , "Row of vehicles for hire" , "site for parking" , "Cab-stand" .)
