It appears there's anger about one (6)

Ross

I believe the answer is:

wraith

I'm a little stuck... Click here to teach me more about this clue!

'it appears there's anger' is the definition.
The definition suggests a singular noun which matches the answer.

'one' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'wrath' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'about' is the link.

Can you help me to learn more?

(Other definitions for wraith that I've seen before include "Ghost or spectral appartition" , "Apparition, phantom, spirit" , "'Ghost, spectre (6)'" , "Presence" , "Ghost-like apparition" .)
