Profanity from guru admitting constant anger (9)
I believe the answer is:
sacrilege
'profanity' is the definition.
(I've seen this before)
'guru admitting constant anger' is the wordplay.
'guru' becomes 'sage' (synonyms).
'admitting' indicates putting letters inside.
'constant' becomes 'c' (mathematical abbreviation).
'anger' becomes 'rile' (I've seen this before).
'c'+'rile'='crile'
'sage' placed around 'crile' is 'SACRILEGE'.
'from' is the link.
(Other definitions for sacrilege that I've seen before include "Religious violation" , "Disrespect or damage to something sacred" , "Misuse of something sacred" , "Violation of something sacred" , "Violation of a holy thing" .)
