Decide, at one point, to take the French to court (5)
I believe the answer is:
elect
'decide' is the definition.
(I know that elect is a more specific form of the action choose)
'one point to take the french to court' is the wordplay.
'one point' becomes 'e' (compass point).
'to take' means one lot of letters go next to another.
'the french' becomes 'le' ('the' in French).
'to court' becomes 'ct' (abbreviation used in road names).
'e'+'le'+'ct'='ELECT'
'at' is the link.
(Other definitions for elect that I've seen before include "Choose by ballot" , "Select; chosen" , "Put into power through the ballot box" , "Waiting to get into office" , "Return" .)
