Do, kind of, have a partner (7)
I believe the answer is:
consort
'partner' is the definition.
('consort' can be a synonym of 'partner')
'do kind' is the wordplay.
'do' becomes 'con'.
'kind' becomes 'sort' ('sort' can be a synonym of 'kind'**).
'con'+'sort'='CONSORT'
'of have a' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for consort that I've seen before include "wife, perhaps" , "Companion; ship sailing with another" , "A monarch's spouse" , "Small group; spouse" , "Husband or wife of a monarch" .)
