Latest version at university seen before appointment (6)
I believe the answer is:
update
'latest version' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'at university seen before appointment' is the wordplay.
'at university' becomes 'up' ('up' can mean studying at university).
'seen before' says to put letters next to each other.
'appointment' becomes 'date' (synonyms).
'up'+'date'='UPDATE'
Can you help me to learn more?
(Other definitions for update that I've seen before include "Renew" , "Bulletin" , "Modernise, modify" , "Bring to present status, say accounts" , "Something fresh" .)
