Free to speak (7)
I believe the answer is:
deliver
This clue is a double definition.
'free' is the first definition.
(delivering is a kind of freeing)
'speak' is the second definition.
(delivering is a kind of speaking)
'to' acts as a link.
(Other definitions for deliver that I've seen before include "Consign" , "Convey to destination" , "ship" , "Hand over (to someone)" , "Dispatch" .)
