Looks embarrassed when left in the shrubbery (7)
I believe the answer is:
blushes
'looks embarrassed' is the definition.
I can't judge whether this defines the answer.
'left in the shrubbery' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in the' means one lot of letters goes inside another.
'shrubbery' becomes 'bushes' (I've seen this in another clue).
'l' placed into 'bushes' is 'BLUSHES'.
'when' is the link.
Can you help me to learn more?
(Other definitions for blushes that I've seen before include "Reddenings of the face, in embarrassment perhaps" , "Turns red with embarrassment" .)
