Express a view nothing is next to wood (5)
I believe the answer is:
opine
'express a view' is the definition.
(I've seen this before)
'nothing is next to wood' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'is next to' means one lot of letters go next to another.
'wood' becomes 'pine' (pine is a kind of wood**).
'o'+'pine'='OPINE'
(Other definitions for opine that I've seen before include "Express or hold view" , "Say what one thinks" , "Proffer a view" , "State as one's belief" , "Conjecture" .)
