Bond performer finally forges with relatives coming around (7)
I believe the answer is:
brosnan
'bond performer finally forges' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'with relatives coming around' is the wordplay.
'with' means one lot of letters go next to another.
'relatives' becomes 'bros' (bro is short for brother).
'coming around' becomes 'nan' (I can't explain this - if you can you should give a lot more credence to this answer).
'bros' next to 'nan' is 'BROSNAN'.
Can you help me to learn more?
(Other definitions for brosnan that I've seen before include "Pierce --, Irish actor" , "Pierce --, James Bond actor" , "Pierce --, 52 Down actor" .)
