Seen in the theatre, it's also in the kitchen (4)
I believe the answer is:
heat
'the kitchen' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'seen in the theatre it's also' is the wordplay.
'seen in' indicates a hidden word.
'HEAT' is hidden in the letters of 'theatre also'.
'in' is the link.
Can you help me to learn more?
(Other definitions for heat that I've seen before include "Warmth - gossip mag" , "Provide warmth" , "Vehemence" , "Warmth - passion" , "early round" .)
