Reckless Knight starts to incite kids entering a labyrinth (8)
I believe the answer is:
kamikaze
'reckless' is the definition.
(I've seen this before)
'knight starts to incite kids entering a labyrinth' is the wordplay.
'knight' becomes 'k'.
'starts to' suggests taking the first letters.
'entering' indicates putting letters inside.
'labyrinth' becomes 'maze' ('maze' can be a synonym of 'labyrinth').
The initial letters of 'incite kids' is 'ik'.
'a'+'maze'='amaze'
'ik' put inside 'amaze' is 'amikaze'.
'k'+'amikaze'='KAMIKAZE'
(Other definitions for kamikaze that I've seen before include "Aircraft used for suicide missions by Japan in World War II" , "Foolhardy" , "Suicidal like Japanese pilot in WW2" , "Japanese pilot on a suicide attack" , "Self-destructive (from Japanese WW2 pilots)" .)
