Spirit of anger around one (6)
I believe the answer is:
wraith
'spirit' is the definition.
(I've seen this in another clue)
'anger around one' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'anger' could be 'wrath' (wrath is a kind of anger) and 'wrath' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
(Other definitions for wraith that I've seen before include "Making an emotional appeal" , "Ghostly figure" , "'Ghost, spectre (6)'" , "Wrath I directed at spirit" , "looking pale and thin" .)
