The Telegraph's hosting party, getting bouquet (5)
I believe the answer is:
odour
'bouquet' is the definition.
(I've seen this before)
'the telegraph's hosting party' is the wordplay.
'the telegraph's' becomes 'our' (I can't justify this - if you can you should believe this answer much more).
'hosting' means one lot of letters goes inside another (inserted letters are welcomed in or hosted).
'party' becomes 'do' (do is a kind of party).
'our' enclosing 'do' is 'ODOUR'.
'getting' is the link.
Can you help me to learn more?
(Other definitions for odour that I've seen before include "A smell, good or bad" , "reputation" , "Pong" , "Small, aroma" , "Distinctive smell" .)
