House publication with colleague's final tribute (6)
I believe the answer is:
homage
'tribute' is the definition.
(I have seen 'Public tribute ' mean 'homage' so perhaps 'tribute' could also mean 'homage')
'house publication with colleague's final' is the wordplay.
'house' becomes 'ho' (abbreviation for house**).
'publication' becomes 'mag' (abbreviation for magazine).
'with' is a charade indicator (letters next to each other).
'final' indicates one should take the final letters.
The last letter of 'colleague' is 'e'.
'ho'+'mag'+'e'='HOMAGE'
(Other definitions for homage that I've seen before include "Acknowledgment of superiority" , "Things said as mark of respect" , "Things said to show respect, obeisance" , "Respectful deference" , "Honour or respect shown publicly" .)
