A large basket will be a hindrance (6)
I believe the answer is:
hamper
This might be a double definition.
'a large basket' is the first definition.
'hamper' can be an answer for 'basket' (eg food hamper). I am not sure about the 'a large' bit.
'a hindrance' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'will be' is the link.
Can you help me to learn more?
(Other definitions for hamper that I've seen before include "Restrict, hinder" , "Obstruct with picnic basket" , "Impede with picnic basket?" , "Obstruct or delay with food basket" , "Hinder, impede" .)
