Receiving contrary tip, friend had flutter (9)
I believe the answer is:
palpitate
'flutter' is the definition.
(synonyms)
'receiving contrary tip friend' is the wordplay.
'receiving' means one lot of letters goes inside another.
'contrary' indicates anagramming the letters.
'friend' becomes 'palate' (I am not sure about this - if you are sure you should believe this answer much more).
'tip' anagrammed gives 'pit'.
'pit' going into 'palate' is 'PALPITATE'.
'had' acts as a link.
Can you help me to learn more?
(Other definitions for palpitate that I've seen before include "Throb rapidly" , "Beat abnormally quickly" , "Rapidly beat" , "flutter" , "quake" .)
