I will not run out of highway (9)
I believe the answer is:
intestate
'i' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'not run out of highway' is the wordplay.
'not' is a deletion indicator.
'run out' becomes 'RO' (cricket abbreviation).
'of' becomes 'o''.
'highway' becomes 'interstate' (interstate is a highway between two US states).
'o'+'interstate'='ointerstate'
'ointerstate' with 'ro' taken out is 'INTESTATE'.
'will' is the link.
Can you help me to learn more?
(Other definitions for intestate that I've seen before include "Unwilling" , "Dying thus, one has left no will" , "One without will" , "Undecided about who should inherit" , "Not having written a will before death" .)
