Registered arrival listening to the hubbub in Prague, say? (7,2)
I believe the answer is:
checked in
'registered arrival listening' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'the hubbub in prague say?' is the wordplay.
I cannot really understand how this works, but
'hubbub' could be 'din' (I've seen this in another clue) and 'din' is found in the answer.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for checked in that I've seen before include "At reception" , "Registered for flight" .)
