Puffer at home gets healthier (7)
I believe the answer is:
inhaler
'puffer' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'home gets healthier' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'gets' is a charade indicator (letters next to each other).
'healthier' becomes 'haler' ('hale' can be similar in meaning to 'healthy').
'in'+'haler'='INHALER'
'at' acts as a link.
Can you help me to learn more?
(Other definitions for inhaler that I've seen before include "Uninhibited smoker" , "Medical device" , "Dispenser of vapour for the nose or lungs" , "Asthmatic's device" , "way of taking drugs" .)
