Turned around space-time docking procedure (7)
I believe the answer is:
moorage
'docking procedure' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'turned around space-time' is the wordplay.
'turned around' is a reversal indicator.
'space' becomes 'room' (enough space or room to do something).
'time' becomes 'age' (an age is a period of time).
'room' in reverse letter order is 'moor'.
'moor'+'age'='MOORAGE'
Can you help me to learn more?
(Other definitions for moorage that I've seen before include "Anchorage N or charge for using it!" , "Berthing fee" , "Charge for leaving boat" , "Making fast" , "Fee for securing boat" .)
