North European became worried about current bargain (9)
I believe the answer is:
negotiate
'bargain' is the definition.
(I know that bargain is a kind of negotiate)
'north european became worried about current' is the wordplay.
I cannot quite see how this works, but
'north' could be 'n' (abbreviation) and 'n' is found within the answer.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found within the answer.
'became' could be 'got' ('get' can be a synonym of 'become') and 'got' is located in the answer.
'worried' could be 'ate' (something worrying may eat someone up) and 'ate' is present in the answer.
'current' could be 'i' (symbol for electric current) and 'i' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for negotiate that I've seen before include "as diplomat does" , "Pass round" , "Discuss the terms of an arrangement" , "Bring about by mutual agreement" , "Try to reach agreement through discussion" .)
