Tall person might accidentally open farmer's carefully wrapped load (8)
I believe the answer is:
beanpole
'carefully wrapped load' is the definition.
The definition suggests a singular noun which matches the answer.
'tall person might accidentally open farmer's' is the wordplay.
I cannot really understand how this works, but
'person' could be 'pol' (pol is a kind of person) and 'pol' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for beanpole that I've seen before include "pea stick" , "one tall and thin" , "Runners depend on this" , "Plant support - thin person" , "tall skinny person" .)
