A low gear, in some strange way, is making it fast (7)
I believe the answer is:
moorage
'a low gear in some strange way is making it fast' is the definition.
I can't judge whether this defines the answer.
'low gear in some strange way is making it fast' is the wordplay.
I cannot quite see how this works, but
'low' could be 'moo' (both can mean to make a cow noise) and 'moo' is located in the answer.
an anagram of 'gear' is 'rage' which is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for moorage that I've seen before include "Making fast" , "Place for a ship to make fast" , "Berthing fee" , "Fee paid for tying up a boat" , "Securing of craft" .)
