Chap to tear out an appliance (6)
I believe the answer is:
heater
'an appliance' 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 don't see?
'chap to tear out' is the wordplay.
'chap' becomes 'he' ().
'to' means one lot of letters go next to another.
'out' indicates an anagram (out can mean wrong or inaccurate).
'tear' is an anagram of 'ater'.
'he'+'ater'='HEATER'
Can you help me to learn more?
(Other definitions for heater that I've seen before include "Warming device" , "Room warmer" , "Source of warmth; gun" , "fire" , "Radiator" .)
