Trauma surrounding rampant ram in clover (8)
I believe the answer is:
shamrock
'clover' is the definition.
(shamrock is a kind of clover)
'trauma surrounding rampant ram' is the wordplay.
'trauma' becomes 'shock' (I've seen this before**).
'surrounding' indicates putting letters inside.
'rampant' indicates an anagram (I've seen this in other clues).
'ram' anagrammed gives 'amr'.
'shock' placed around 'amr' is 'SHAMROCK'.
'in' is the link.
(Other definitions for shamrock that I've seen before include "Irish national symbol" , "Clover-like plant" , "The national Irish trefoil" , "Symbol of Ireland" , "Sign of first part of 10 [IRISH [SEA]]" .)
