Daring chap to stand in for principal? (8)
I believe the answer is:
stuntman
'daring' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'chap to stand in for principal?' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'to' means one lot of letters go next to another (I've seen this in other clues).
'stand in for principal?' becomes 'stunt' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'man' after 'stunt' is 'STUNTMAN'.
Can you help me to learn more?
(Other definitions for stuntman that I've seen before include "one with special role in film" , "He acts riskily" , "Double for a film's dangerous scenes" , "Performer of dangerous acts in films etc" , "Movie extra who performs dangerous feats" .)
