There’s a box right by the hole (6)
I believe the answer is:
crater
'the hole' is the definition.
(thesaurus)
'there's a box right by' is the wordplay.
'there's a box' becomes 'crate' (I've seen this before).
'right' becomes 'r' (common abbreviation).
'by' says to put letters next to each other.
'crate'+'r'='CRATER'
(Other definitions for crater that I've seen before include "Moon cavity" , "Large hole" , "big hole" , "Caldera" , "Volcano opening" .)
