Angry and confused, sit in hole (7)
I believe the answer is:
hostile
'angry' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'confused sit in hole' is the wordplay.
'confused' indicates an anagram.
'in' means one lot of letters goes inside another.
'sit' with letters rearranged gives 'sti'.
'sti' inserted within 'hole' is 'HOSTILE'.
'and' is the link.
Can you help me to learn more?
(Other definitions for hostile that I've seen before include "The soil strangely is unfriendly" , "Unkind" , "Showing angry opposition" , "Antagonistic" , "harsh" .)
