At risk of death and really annoyed! (10)
I believe the answer is:
endangered
'at risk' is the definition.
(I've seen this before)
'death and really annoyed' is the wordplay.
'death' becomes 'end' (synonyms).
'and' means one lot of letters go next to another.
'really annoyed' becomes 'angered' (made angry or annoyed. I am not sure about the 'really' bit.).
'end'+'angered'='ENDANGERED'
'of' is the link.
Can you help me to learn more?
(Other definitions for endangered that I've seen before include "compromised" , "Threatened" , "in a perilous situation" , "put at risk" , "Vulnerable" .)
