The crane swinging at the back is no help at all (9)
I believe the answer is:
hindrance
'no help at all' is the definition.
I can't judge whether this definition defines the answer.
'the crane swinging at the back' is the wordplay.
'swinging' is an anagram indicator.
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the back' becomes 'hind' (I've seen this before**).
'crane' with letters rearranged gives 'rance'.
'rance' put after 'hind' is 'HINDRANCE'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for hindrance that I've seen before include "Nicer hand (anag.)" , "Chain nerd up - it delays progress" , "Delay to overcome" , "Obstacle" , "barrier" .)
