Joins up with partners (10)
I believe the answer is:
associates
This could be a double definition.
'joins up' is the first definition.
The answer and definition can be both to do with social activities as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?
'partners' is the second definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see an association between them that I don't see?
'with' is the link.
Can you help me to learn more?
(Other definitions for associates that I've seen before include "Hangs out with" , "Colleagues" , "mates" , "Companions" .)
