Fly round a tree in cockily spectacular style (6)
I believe the answer is:
flashy
'cockily spectacular style' is the definition.
I can't tell whether this defines the answer.
'fly round a tree' is the wordplay.
'round' means one lot of letters goes inside another.
'a tree' becomes 'ash' (ash is a kind of tree).
'fly' enclosing 'ash' is 'FLASHY'.
'in' is the link.
Can you help me to learn more?
(Other definitions for flashy that I've seen before include "Ostentatious - glittering" , "Vulgar" , "Loud" , "Gaudy or showy" , "Cheap and showy" .)
