Parting expressions were translated during trips (9)
I believe the answer is:
farewells
'parting expressions' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'were translated during trips' is the wordplay.
'translated' is an anagram indicator.
'during' indicates putting letters inside.
'trips' becomes 'falls' (fall is a kind of trip).
'were' is an anagram of 'rewe'.
'rewe' placed within 'falls' is 'FAREWELLS'.
Can you help me to learn more?
(Other definitions for farewells that I've seen before include "spoken last words" , "They may be fond" .)
