Our ordeal involved getting hold of lost deposit in foreign bank (10)
I believe the answer is:
eurodollar
'deposit in foreign bank' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'our ordeal involved getting hold of lost' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'our' is 'uro' which is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for eurodollar that I've seen is " International currency medium".)
