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 (in sense of 'inviting in').
'a person' becomes 'each' (I can't explain this - if you can you should believe this answer much more).
'ring' placed around '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" .)
