Suit that cannot be worn, like pumps (6)
I believe the answer is:
hearts
This might be a double definition.
'suit that cannot be worn' is the first definition.
'hearts' can be an answer for 'suit' (hearts is a playing card suit). I'm not sure about the rest of the definition.
'pumps' is the second definition.
('heart' can be a synonym of 'pump')
'like' is the link.
Can you help me to learn more?
(Other definitions for hearts that I've seen before include "Body pumps" , "Suit for vital organs" , "Red playing cards" , "See 23" , "Card suits in bodies" .)
