Sharpness about current role involving two groups (9)

I believe the answer is:

bipartite

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

'involving two groups' is the definition.
I can't judge whether this defines the answer.

'sharpness about current role' is the wordplay.
'sharpness' becomes 'bite' (synonyms).
'about' is an insertion indicator.
'current' becomes 'I' (physics symbol).
'role' becomes 'part' (eg a part or role in a film).
'i'+'part'='ipart'
'bite' going around 'ipart' is 'BIPARTITE'.

Can you help me to learn more?

(Another definition for bipartite that I've seen is " Involving two sides".)

I've seen this clue in The Irish Times.
