Disheartened consul, in the centre of Paris, uses web to get instrument (8)
I believe the answer is:
clarinet
'instrument' is the definition.
(I know that clarinet is a clarinet)
'disheartened consul in the centre of paris uses web' is the wordplay.
'disheartened' says to hollow out the word (remove centre letters) (the middle or heart is removed).
'in the centre of' indicates the central letters (I've seen 'in the centre' mean this).
'uses web' becomes 'net' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'consul' with its centre removed is 'cl'.
The centre of 'paris' is 'ari'.
'cl'+'ari'+'net'='CLARINET'
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for clarinet that I've seen before include "musician" , "Wind instrument made from Clare tin" , "It's for playing" , "Find an instrument in claret" , "Source of music" .)
