A lump of wood agent sent over for trellis (7)
I believe the answer is:
pergola
'trellis' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'a lump of wood agent sent over' is the wordplay.
'lump of wood' becomes 'log' (I am not sure about this - if you are sure you should believe this answer much more).
'agent' becomes 'rep' (short for representative).
'sent over' says the letters should be written in reverse.
'a'+'log'+'rep'='alogrep'
'alogrep' reversed gives 'PERGOLA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for pergola that I've seen before include "lattice" , "Overhanging garden structure" , "Horizontal trellis" , "Structure for climbers" , "Trellis for climbing plants" .)
