Reluctant to do anything as the guy is back on a gallery (8)
I believe the answer is:
hesitate
'reluctant to do anything' is the definition.
I can't judge whether this definition defines the answer.
'the guy is back on a gallery' is the wordplay.
'the guy' becomes 'he'.
'back' shows that the letters should be reversed in order.
'on' means one lot of letters go next to another.
'a gallery' becomes 'tate' (Tate Modern, Tate Britain etc).
'is' backwards is 'si'.
'he'+'si'+'tate'='HESITATE'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for hesitate that I've seen before include "Be in two minds" , "Dither, waver" , "He who does it may be lost" , "Stall" , "Falter, waver" .)
