A way to speak (7)
I believe the answer is:
stutter
'speak' is the definition.
(I know that stutter is a more specific form of the action speak)
'a way to' is the wordplay.
'a way' becomes 'st' (abbreviation for street).
'to' becomes 'utter' (I can't justify this - if you can you should give a lot more credence to this answer).
'st'+'utter'='STUTTER'
Can you help me to learn more?
(Other definitions for stutter that I've seen before include "Struggle with one's words" , "Stumble over words" , "Falter" , "Struggle to speak" , "Stammer" .)
