It can be fun to say goodbye at journey's end (5)
I believe the answer is:
party
'it can be fun' is the definition.
The definition suggests a singular noun which matches the answer.
'say goodbye at journey's end' is the wordplay.
'say goodbye' becomes 'part' (I've seen this in another clue).
'at' says to put letters next to each other.
'end' suggests the final letters.
The final letter of 'journey' is 'y'.
'part'+'y'='PARTY'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for party that I've seen before include "Political organization" , "Social gathering; person" , "Political organisation" , "Political group; function" , "Social function" .)
