Impressive standing in court, having smuggled yen (6)
I believe the answer is:
cachet
'impressive standing' is the definition.
'cachet' can be an answer for 'standing' (thesaurus). I'm not certain of the 'impressive' bit.
'court having smuggled yen' is the wordplay.
'court' becomes 'ct' (abbreviation used in road names).
'having' indicates putting letters inside.
'smuggled yen' becomes 'ache' (synonyms. I am not sure about the 'smuggled' bit.).
'ct' placed around 'ache' is 'CACHET'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cachet that I've seen before include "Distinguishing mark or seal" , "Seal; mark of prestige" , "Distinguishing feature" , "Kudos" , "Mark of approval" .)
