Dance is more attractive when carrying a hat (3,1,5)
I believe the answer is:
cut a caper
'dance' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'more attractive when carrying a hat' is the wordplay.
'more attractive' becomes 'cuter' ('cute' can be similar in meaning to 'attractive').
'when carrying' is an insertion indicator.
'hat' becomes 'cap' (cap is a type of hat).
'a'+'cap'='acap'
'cuter' going around 'acap' is 'CUT A CAPER'.
'is' is the link.
Can you help me to learn more?
(Other definitions for cut a caper that I've seen before include "Bound" , "to make a start on tartare sauce" , "Make a playful skipping movement" , "When making tartar sauce, one has to" , "Skip or jump playfully" .)
