Put your foot down? (4)
But I've got no explanation for this one! Could you help me understand?
(Other definitions for stamp that I've seen before include "Postal token" , "squash?" , "contributions?" , "Impress; postage sticker" , "What to put on 7 before putting in 15" .)
'foot down' is the definition.
'tread' can be an answer for 'foot' (treading is a kind of footing). I'm not certain of the 'down' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
