Give a lance to our cool-headed youngster in his jousting gear? (6-4)
I believe the answer is:
armour-clad
'jousting gear?' is the definition.
I can't judge whether this defines the answer.
'give a lance to our cool-headed youngster in his' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
'youngster' could be 'lad' (a young boy) and 'lad' is present in the answer.
'to our' could be 'our' and 'our' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for armour-clad that I've seen is " Covered by heavy metal protection".)
