Sympathy for all that trouble with foreign money lost (7)
I believe the answer is:
thought
'sympathy' is the definition.
(thesaurus)
'for all that trouble with foreign money lost' is the wordplay.
I cannot really see how this works, but
'for all that' could be 'though' ('for all that' can mean 'though' or 'although') and 'though' is found in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for thought that I've seen before include "just a trifle" , "Meditation" , "That's an idea" , "Considered, believed" , "Philosopher must master this" .)
