Costumes which chatterboxes like (5)
I believe the answer is:
togas
'costumes' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe there's a link between them I don't understand?
'chatterboxes like' is the wordplay.
'chatterboxes' becomes 'tog' (I can't explain this - if you can you should give a lot more credence to this answer).
'like' becomes 'as'.
'tog'+'as'='TOGAS'
'which' is the link.
Can you help me to learn more?
(Other definitions for togas that I've seen before include "Roman garments" , "garments worn by ancient Romans" , "clothing" , "What some ancient citizens wore" .)
