With very Scottish bridge, etc. (3,2,5)
I believe the answer is:
and so forth
'etc' is the definition.
(I've seen this before)
'with very scottish bridge' is the wordplay.
'with' becomes 'and'.
'very' becomes 'so' (both can mean 'extremely').
'scottish bridge' becomes 'forth' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and'+'so'+'forth'='AND SO FORTH'
Can you help me to learn more?
(Other definitions for and so forth that I've seen before include "etc." , "Et cetera" , "implies others of the same type" , "Along with other things" , "imagine what follows" .)
