Internet suffix given to Yankee — what a party! (4)
I believe the answer is:
orgy
'what a party' is the definition.
(I've seen this before)
'internet suffix given to yankee' is the wordplay.
I cannot really understand how this works, but
'yankee' could be 'y' (phonetic alphabet: alpha, bravo, charlie etc.) and 'y' is found in the answer.
The remaining letters 'org' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for orgy that I've seen before include "Wild indulgence" , "Rumpy-pumpy party" , "Saturnalia" , "Wild revelry" , "Wild, debauched gathering" .)
