Begin lies with stab wound in front of hospital (9)
I believe the answer is:
establish
'begin' is the definition.
(thesaurus)
'lies with stab wound in front of hospital' is the wordplay.
'with' says to put letters next to each other.
'wound' indicates anagramming the letters (wound can mean twisted or turned around).
'in front of' suggests taking the first letters.
The initial letter of 'hospital' is 'h'.
'lies' put after 'stab' is 'stablies'.
'stablies' with letters rearranged gives 'establis'.
'establis'+'h'='ESTABLISH'
(Other definitions for establish that I've seen before include "form" , "Found - institute" , "Set up on permanent basis, or show to be true" , "Found or authenticate" , "Set up or settle firmly in place" .)
