Tack on, append (5)

Ross

I believe the answer is:

affix

I believe this is a double definition.

'tack on' is the first definition.
(I've seen this in another clue)

'append' is the second definition.
(synonyms)

(Other definitions for affix that I've seen before include "Glue" , "Attach" , "Join" , "Append" , "Fasten (to something)" .)

I've seen this clue in The Sun.
