Trying experience with nothing right about transaction (6)
I believe the answer is:
ordeal
'trying experience' is the definition.
(I've seen this before)
'nothing right about transaction' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'right' becomes 'R' (common abbreviation).
'about transaction' becomes 'deal' (deal is a kind of transaction. I am not sure about the 'about' bit.).
'o'+'r'+'deal'='ORDEAL'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for ordeal that I've seen before include "Severe trial" , "Ancient form of trial" , "very hard test" , "Difficult experience, a tough time" , "Loader (anag.)" .)
