Speaker finds gold by a hill (6)
I believe the answer is:
orator
'speaker' is the definition.
(I know that orator is a type of speaker)
'gold by a hill' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'by' says to put letters next to each other.
'hill' becomes 'tor' (tor is a kind of hill).
'or'+'a'+'tor'='ORATOR'
'finds' acts as a link.
(Other definitions for orator that I've seen before include "Formal speech maker" , "Eloquent public speaker" , "A fluent public speaker" , "An impressive public speaker" , "he can talk" .)
