Jeer team starting in Wellington (4)
I believe the answer is:
boot
'wellington' is the definition.
(I've seen this before)
'jeer team starting' is the wordplay.
'jeer' becomes 'boo' (I've seen this before).
'starting' indicates taking the first letters.
The first letter of 'team' is 't'.
'boo'+'t'='BOOT'
'in' is the link.
(Other definitions for boot that I've seen before include "Luggage compartment" , "Hard kick; part of car" , "Sack" , "They call it a trunk in the US" , "Stout shoe" .)
