Large hole for container, right? (6)
I believe the answer is:
crater
'large hole' is the definition.
(large hole in the ground)
'container right?' is the wordplay.
I cannot really understand how this works, but
'container' could be 'crate' (crate is a kind of container) and 'crate' is present in the answer.
'right?' could be 'r' (abbreviation) and 'r' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for crater that I've seen before include "Bowl-shaped cavity as on volcano peak" , "Volcanic cavity" , "Capital of Virginia" , "Volcanic depression" , "Large bowl-shaped hollow" .)
