Plant journalist receiving honour (5)
I believe the answer is:
embed
'plant' is the definition.
(I've seen this before)
'journalist receiving honour' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'receiving' means one lot of letters goes inside another.
'honour' becomes 'mbe'.
'ed' going around 'mbe' is 'EMBED'.
(Other definitions for embed that I've seen before include "bringing plant inside" , "one placed in a military unit" , "Put entirely inside something else" , "Fix in the mind" , "Fix fast in something solid" .)
