A football team always has weight (7)
I believe the answer is:
everton
'a football team' is the definition.
(I've seen this before)
'always has weight' is the wordplay.
'always' becomes 'ever' (synonyms).
'has' says to put letters next to each other.
'weight' becomes 'ton' (unit of weight).
'ever'+'ton'='EVERTON'
(Other definitions for everton that I've seen before include "'The Toffees' FC" , "Merseyside soccer team" , "Liverpool FC" , "Liverpool football team" , "Merseyside football team" .)
