Anxious time with currency beginning to drop (8)
I believe the answer is:
troubled
'anxious' is the definition.
(I've seen this before)
'with currency beginning to drop' is the wordplay.
'with' means one lot of letters goes inside another.
'currency' becomes 'rouble' (Russian rouble**).
'beginning' suggests taking the first letters.
The initial letters of 'to drop' is 'td'.
'rouble' put within 'td' is 'TROUBLED'.
'time' is the link.
(Other definitions for troubled that I've seen before include "Inconvenienced" , "Disturbed, bothered" , "Disquieted, upset" , "Caused distress to" , "Distressed, perturbed" .)
