Journey ending in short farewell (4)
I believe the answer is:
trip
'journey' is the definition.
(I know that journey is a more specific form of the action the trip)
'ending in short farewell' is the wordplay.
'ending in' indicates one should take the final letters.
'farewell' becomes 'rip' (I can't explain this - if you can you should give a lot more credence to this answer).
The last letter of 'short' is 't'.
't'+'rip'='TRIP'
Can you help me to learn more?
(Other definitions for trip that I've seen before include "... the light fantastic to dance" , "holiday" , "Set off for" , "Journey, excursion" , "Jaunt" .)
