Youngster in cot, perhaps with sharp edge (6)
I believe the answer is:
bladed
'with sharp edge' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'youngster in cot' is the wordplay.
'youngster' becomes 'lad' (I've seen this in other clues).
'in' indicates putting letters inside.
'cot' becomes 'bed' (I've seen this in other clues).
'lad' put within 'bed' is 'BLADED'.
'perhaps' is the link.
Can you help me to learn more?
(Another definition for bladed that I've seen is " Like oars".)
