Get friendly with James (4)
I believe the answer is:
bond
'get' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bond that I've seen before include "James ...., fiction's 007" , "relationship" , "Obligation" , "Affinity" , "Something that joins together, or a financial document" .)
