Bill harnesses psychic ability to foretell (7)
I believe the answer is:
bespeak
'foretell' 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?
'bill harnesses psychic ability' is the wordplay.
I cannot really understand how this works, but
'bill' could be 'peak' (synonyms) and 'peak' is present in the answer.
The remaining letters 'bes' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for bespeak that I've seen before include "Provide evidence" , "Bear witness" , "Apply for" .)
