It's a bit like sacking a German (7)
I believe the answer is:
hessian
'german' is the definition.
(someone from the German state of Hesse)
'it's a bit like sacking a' is the wordplay.
I cannot really understand how this works, but
'it's' could be 'es' ('e' can mean 'electronic' which is similar to 'IT') and 'es' is found within the answer.
'a' could be 'an' and 'an' is found within the answer.
'bit' could be 'i' (resembles 1, a binary digit or bit) and 'i' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hessian that I've seen before include "sackcloth?" , "Coarse cloth" , "Coarse fabric used in sacks" , "Cloth made from jute" , "It's rather like sacking" .)
