We get a headpiece that's maybe too small (3)
I believe the answer is:
wee
'small' is the definition.
(Scottish term for small)
'we get a headpiece that's maybe too' is the wordplay.
I cannot quite understand how this works, but
'we' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for wee that I've seen before include "Minute" , "Slash" , "Tiny (Scot)" , "It's small in Scotland" , "Small like Willie Winkie" .)
