Flock member is hot with embarrassment (8)
I believe the answer is:
sheepish
'with embarrassment' is the definition.
(I've seen this before)
'flock member is hot' is the wordplay.
'flock member' becomes 'sheep' (I can't justify this - if you can you should give a lot more credence to this answer).
'hot' becomes 'h' (abbreviation eg on taps).
'sheep'+'is'+'h'='SHEEPISH'
Can you help me to learn more?
(Other definitions for sheepish that I've seen before include "Embarrassed through shame; ovine" , "Embarrassed -- like ewe!" , "Embarrassed in woolly way?" , "Embarrassedly shy" , "Shamefaced, embarrassed" .)
