Tribute in vacuous Hello! publication by European (6)
I believe the answer is:
homage
'tribute' is the definition.
(an homage is respect paid to someone)
'vacuous hello publication by european' is the wordplay.
'vacuous' says to hollow out the word (remove centre letters).
'publication' becomes 'mag' (abbreviation for magazine).
'by' says to put letters next to each other.
'european' becomes 'E' (abbreviation e.g. EU).
'hello' with its middle removed is 'ho'.
'ho'+'mag'+'e'='HOMAGE'
'in' is the link.
(Other definitions for homage that I've seen before include "Tribute, reverence" , "Public tribute" , "Show of respect to someone" , "respectful acknowledgment" , "Honour or respect shown publicly" .)
