Picking up a hoop for the others to go through (9)
I believe the answer is:
arresting
'picking up' is the definition.
('arrest' can be a synonym of 'pick up')
'a hoop for the others to go through' is the wordplay.
'hoop' becomes 'ring' (synonyms).
'for' means one lot of letters go next to another.
'the others' becomes 'rest' (I've seen this before).
'to go through' indicates putting letters inside.
'a'+'ring'='aring'
'aring' enclosing 'rest' is 'ARRESTING'.
(Other definitions for arresting that I've seen before include "Police work" , "Running in" , "Lovely" , "Taking into custody for being eye-catching?" , "remarkable" .)
