Put around an open offer and conclude successfully (3,3)
I believe the answer is:
pan out
'conclude successfully' is the definition.
'pan out' can be an answer for 'conclude'. I'm unsure of the 'successfully' bit.
'put around an open offer' is the wordplay.
'around' means one lot of letters goes inside another.
'open' says to take the initial letters (take the opening letter).
The initial letter of 'offer' is 'o'.
'an'+'o'='ano'
'put' enclosing 'ano' is 'PAN OUT'.
'and' is the link.
Can you help me to learn more?
(Other definitions for pan out that I've seen before include "Conclude, end up well" , "Have acceptable result - exclude frying vessel" , "End up, turn out well" .)
