Distress? Time to get foreign currency (7)
I believe the answer is:
trouble
'distress?' is the definition.
(distressing is a kind of troubling)
'time to get foreign currency' is the wordplay.
'time' becomes 't'.
'to get' says to put letters next to each other.
'foreign currency' becomes 'rouble' (I've seen this in other clues).
't'+'rouble'='TROUBLE'
(Other definitions for trouble that I've seen before include "Distress, upset or worry" , "Nuisance, bother" , "Pains" , "Conflict" , "Disquiet" .)
