Agree to gold even if more money (9)
I believe the answer is:
authorise
'agree' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
'gold even if more money' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'even if' becomes 'tho'' (I've seen this in another clue).
'more' says to put letters next to each other (some letters added to the previous ones).
'money' becomes 'rise' (I have seen 'more money' mean 'rise' so perhaps 'money' could also mean 'rise').
'au'+'tho'+'rise'='AUTHORISE'
'to' is the link.
Can you help me to learn more?
(Other definitions for authorise that I've seen before include "Give power to or sanction" , "OK" , "Sanction, empower" , "warrant" , "I share out (anag.)" .)
