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.
Perhaps there's a link between them I don't understand?
'seen in the theatre it's also' is the wordplay.
'seen in' indicates a hidden word.
'HEAT' can be found hidden inside '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" .)
