Wind plan embarrassed, on reflection (7)
I believe the answer is:
meander
'wind' is the definition.
(to meander is to wind around)
'plan embarrassed on reflection' is the wordplay.
'plan' becomes 'mean'.
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'on reflection' says the letters should be written backwards.
'red' written backwards gives 'der'.
'mean'+'der'='MEANDER'
(Other definitions for meander that I've seen before include "Red mane (anag) - roam aimlessly" , "an Indo-European river" , "Wander aimlessly like a stream" , "Snake" , "Wander in leisurely way, like stream" .)
