British monarch keeps fuel in home heater (6)
I believe the answer is:
boiler
'home heater' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'british monarch keeps fuel' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'monarch' becomes 'ER' (abbreviation for Elizabeth Regina, British Queen).
'keeps' means one lot of letters goes inside another.
'fuel' becomes 'oil' (I've seen this in another clue).
'b'+'er'='ber'
'ber' placed around 'oil' is 'BOILER'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for boiler that I've seen before include "Container to heat water or tough fowl" , "Water heater" , "Water-heater" , "Container for heating water or a tough fowl" , "Steam-producer" .)
