Said to push in opposite directions (6)
I believe the answer is:
'said' is the definition.
(I've seen this before)
'push in opposite directions' is the wordplay.
'push' becomes 'poke' (I can't justify this - if you can you should believe this answer much more).
'in' means one lot of letters goes inside another.
'opposite directions' becomes 'SN' (opposite compass points).
'poke' going within 'sn' is 'SPOKEN'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for spoken that I've seen before include "Voiced" , "Oral" , "Uttered through the medium of speech" , "released from trap" , "Said" .)
