In a way, women put their heart into the show! (7)
I believe the answer is:
somehow
'in a way' is the definition.
(I've seen this in another clue)
'women put their heart into the show' is the wordplay.
'women' becomes 'om' (I can't explain this - if you can you should give a lot more credence to this answer).
'put' says to put letters next to each other.
'heart' means to look at the middle letters.
'into' indicates putting letters inside.
The middle of 'their' is 'e'.
'om'+'e'='ome'
'ome' going within 'show' is 'SOMEHOW'.
Can you help me to learn more?
(Other definitions for somehow that I've seen before include "In a way not yet specified" , "For some unspecified reason" , "In an unspecified manner" , "One way or another" , "In an unspecified way" .)
