Highly suspicious soldier starts to notice odd incidents daily (8)
I believe the answer is:
paranoid
'highly suspicious' is the definition.
'paranoid' can be an answer for 'suspicious' (I've seen this before). I'm not certain of the 'highly' bit.
'soldier starts to notice odd incidents daily' is the wordplay.
'soldier' becomes 'para' (para is a kind of soldier).
'starts to' says to take the initial letters.
The first letters of 'notice odd incidents daily' is 'noid'.
'para'+'noid'='PARANOID'
Can you help me to learn more?
(Other definitions for paranoid that I've seen before include "Afflicted with delusions of persecution" , "Suffering delusions; road pain (anag.)" , "Distrustful" , "mental disorder" , "one given to suspicion" .)
