Getting to arena to welcome a person (8)
I believe the answer is:
reaching
'getting to' is the definition.
('reach' can be a synonym of 'get to')
'arena to welcome a person' is the wordplay.
'arena' becomes 'ring' (eg a boxing ring).
'to welcome' indicates putting letters inside (inserted letters are welcomed in).
'a person' becomes 'each' (I can't justify this - if you can you should give a lot more credence to this answer).
'ring' enclosing 'each' is 'REACHING'.
Can you help me to learn more?
(Other definitions for reaching that I've seen before include "Contacting" , "Connecting" , "Arriving at a place" , "Arriving at, attaining" , "Arriving at a destination or a goal" .)
