Pour a snort to give to the business partner (7)
I believe the answer is:
consort
'the business partner' is the definition.
'consort' can be an answer for 'partner' (synonyms). I am not certain of the 'the business' bit.
'pour a snort to give' is the wordplay.
'pour' becomes 'co' (I can't justify this - if you can you should give a lot more credence to this answer).
'to give' indicates an anagram (I've seen 'gives' mean this).
'snort' is an anagram of 'nsort'.
'co'+'nsort'='CONSORT'
'to' is the link.
Can you help me to learn more?
(Other definitions for consort that I've seen before include "Small group; spouse" , "Marriage partner" , "Keep company" , "wife, perhaps" , "Spouse, partner" .)
