Show the four holding hands with model (8)
I believe the answer is:
newscast
'model' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'show the four holding hands' is the wordplay.
'show' becomes 'news show' (news show is a kind of show).
'the four holding hands' becomes 'cast' (I can't justify this - if you can you should give a lot more credence to this answer).
'news'+'cast'='NEWSCAST'
'with' is the link.
Can you help me to learn more?
(Other definitions for newscast that I've seen before include "media reports" , "Broadcast of recent happenings" , "Current affairs bulletin" , "TV feature maybe" , "Current affairs relay" .)
