Constant choler aroused involving mass burial site (8)
I believe the answer is:
cromlech
'burial site' is the definition.
(type of ancient tomb)
'constant choler aroused involving mass' is the wordplay.
'constant' becomes 'c' (mathematical abbreviation).
'aroused' indicates anagramming the letters (letters roused or stirred up into a new form).
'involving' indicates putting letters inside.
'mass' becomes 'm' (symbol used in Physics e.g. f=ma).
'choler' with letters rearranged gives 'rolech'.
'rolech' placed around 'm' is 'romlech'.
'c'+'romlech'='CROMLECH'
(Other definitions for cromlech that I've seen before include "Ancient stone" , "Prehistoric megalithic tomb" , "stone circle" , "Dolmen, upright prehistoric stones" , "Ancient monument" .)
