Group about to invest funds as the finishing touch (2,3,2,3)
I believe the answer is:
to cap it all
'the finishing touch' is the definition.
I know nothing about this answer so I can't judge whether this works.
'group about to invest funds' is the wordplay.
'group' becomes 'lot'.
'about' says the letters should be written backwards.
'to invest' is an insertion indicator.
'funds' becomes 'capital' (I've seen this before).
'lot' backwards is 'tol'.
'tol' placed around 'capital' is 'TO CAP IT ALL'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for to cap it all that I've seen before include "Finally" , "the worst of the lot" , "As a (frequently unwanted) climax" , "To provide the finishing touch" , "On top of everything else" .)
