House publication with colleague's final tribute (6)
I believe the answer is:
Here is my best explanation:
'tribute' is the definition.
'house publication with colleague's final' is the subsidiary indication.
'house' becomes 'ho'.
'publication' becomes 'mag' (abbreviation for magazine).
'with' means one lot of letters go next to another.
'final' suggests the final letters.
The last letter of 'colleague' is 'e'.
(Other definitions for homage that I've seen before include "Reverent regard", "Honour or respect shown publicly", "Respect - acknowledgement of allegiance", "Formal expression of loyalty to a ruler - pay it", "Public honour and respect", "Show of respect to someone", "Tribute, reverence", "Public show of respect", "Acknowledgment of superiority" and "Dutiful reverence".)
