Associate offering team a boost? (8)
I believe the answer is:
sidekick
'associate' is the definition.
(thesaurus)
'team a boost?' is the wordplay.
'team' becomes 'side' (I've seen this before).
'a boost?' becomes 'kick'.
'side'+'kick'='SIDEKICK'
'offering' acts as a link.
(Other definitions for sidekick that I've seen before include "Person's assistant" , "Fellow adventurer - partner or deputy" , "mate" , "Junior associate" , "Robin perhaps" .)
