British writer with lines depicting forests etc (8)
I believe the answer is:
greenery
'depicting forests etc' is the definition.
I can't tell whether this defines the answer.
'british writer with lines' is the wordplay.
'british writer' becomes 'greene' (graham greene. I am not sure about the 'british' bit.).
'with' means one lot of letters go next to another.
'lines' becomes 'ry' (abbreviation for railway).
'greene'+'ry'='GREENERY'
Can you help me to learn more?
(Other definitions for greenery that I've seen before include "Living foliage or vegetation" , "Foliage etc" , "Decorative boughs" , "Leaves etc" , "Leaves, maybe" .)
