Respirator generally accepted by healthy king (7)
I believe the answer is:
inhaler
'respirator' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'generally accepted by healthy king' is the wordplay.
'generally accepted' becomes 'in' (I've seen this in other clues. I am not sure about the 'generally' bit.).
'by' means one lot of letters go next to another.
'healthy' becomes 'hale' (similar in meaning).
'king' becomes 'r' (r is abbreviation for rex).
'in'+'hale'+'r'='INHALER'
Can you help me to learn more?
(Other definitions for inhaler that I've seen before include "Dispenser of vapour for the nose or lungs" , "Respiratory aid" , "Eg, asthma reliever" , "chest expander?" , "way of taking drugs" .)
