Throwing event: determined to negotiate (6,3)
I believe the answer is:
hammer out
'negotiate' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'throwing event determined' is the wordplay.
'throwing event' becomes 'hammer ' (I've seen this before).
'determined' becomes 'out'.
'hammer'+'out'='HAMMER OUT'
'to' is the link.
Can you help me to learn more?
(Other definitions for hammer out that I've seen before include "Devise with great effort - using mallet etc?" , "Negotiate firmly" .)
