Lesser Arcana, the manifestly cursed thing (8)
I believe the answer is:
anathema
'cursed thing' is the definition.
(I've seen this before)
'lesser arcana the manifestly' is the wordplay.
'ANATHEMA' is hidden within the letters.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for anathema that I've seen before include "Someone or something that is detested" , "One detested, cursed" , "Bete noir" , "target of hate" , "loathsome" .)
