Disseminated, thus, two ways (4)
I believe the answer is:
sown
'disseminated' is the definition.
(I've seen this in another clue)
'thus two ways' is the wordplay.
'two ways' means two replacements for 'way'.
'thus' becomes 'so' (synonyms).
'way' becomes 'w' (Compass direction - West).
'way' becomes 'n' (Compass direction - North).
'so'+'w'+'n'='SOWN'
(Other definitions for sown that I've seen before include "Broadcast" , "(Of seeds) planted" , "Placed in ground as seed" , "set out to grow" , "(Of seed) planted" .)
