Worried woman in Germany making a partial contribution to anything once (7)
I believe the answer is:
fraught
'worried woman in germany making a partial contribution' is the definition.
I can't tell whether this defines the answer.
'anything once' is the wordplay.
I cannot really understand how this works, but
'anything' could be 'aught' ('aught' means anything) and 'aught' is found in the answer.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for fraught that I've seen before include "Charged (with); tense" , "Distressed" , "great anxiety" , "Burdened with anxiety" , "Causing stress" .)
