Think about place to deliver speech (7)
I believe the answer is:
address
I believe this clue is a triple definition!
'think about' is the first definition.
(I've seen this before)
'place' is the second definition.
(addressing is a kind of placing)
'to deliver' acts as a link.
'speech' is the third definition.

(Other definitions for address that I've seen before include "directions in window" , "Place of abode" , "Speech - written on an envelope?" , "Speech; one's home" , "lecture?" .)
