They come across rash in hospital round linked with irregular deaths (8)
I believe the answer is:
hotheads
'they come across rash' is the definition.
The definition suggests an adverb but the answer is not.
'hospital round linked with irregular deaths' is the wordplay.
'hospital' becomes 'H' (abbreviation for hospital).
'round' becomes 'o' (o is a circular letter).
'linked with' says to put letters next to each other.
'irregular' indicates anagramming the letters.
'deaths' is an anagram of 'theads'.
'h'+'o'+'theads'='HOTHEADS'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for hotheads that I've seen before include "They don't think" , "Working together" , "Impetuous folk" , "Impetuous people with fiery temperaments" , "like a sound parachutist?" .)
