Impudence shown by the French teenager originally getting jewellery item (7)
I believe the answer is:
necklet
'jewellery item' is the definition.
'necklet' can be an answer for 'item' (I have seen 'Item of jewellery ' mean 'necklet' so perhaps 'item' could also mean 'necklet'). I'm not certain of the 'jewellery' bit.
'impudence shown by the french teenager originally' is the wordplay.
'impudence' becomes 'neck' (I've seen this before).
'shown by' says to put letters next to each other.
'the french' becomes 'le' ('the' in French).
'originally' indicates taking the first letters.
The first letter of 'teenager' is 't'.
'neck'+'le'+'t'='NECKLET'
'getting' is the link.
Can you help me to learn more?
(Other definitions for necklet that I've seen before include "Item of jewellery" , "Something ornamental" , "Something like a choker" , "Ornament worn above shoulder level" , "Little ornament" .)
