Host offering some Turkish or decaf (5)
I believe the answer is:
horde
'host' is the definition.
(I know that host can be written as horde)
'some turkish or decaf' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'HORDE' can be found hidden inside 'turkish or decaf'.
'offering' is the link.
(Other definitions for horde that I've seen before include "Vast crowd" , "Migratory tribe; army" , "Great crowd" , "Large force" , "Vast multitude" .)
