Like a piper – or four-and-twenty blackbirds? (4)
I believe the answer is:
pied
'like' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pied that I've seen before include "featuring two colours" , "black and white" , "Piper thus portrayed once" , "in various colours" , "varying in colour" .)
