Screening rate of movement doctor may see breathing problem (9)
I believe the answer is:
emphysema
'see breathing problem' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'screening rate of movement doctor' is the wordplay.
I cannot quite see how this works, but
'rate' could be 'mph' (mph is a kind of rate) and 'mph' is located in the answer.
This explanation may well be incorrect...
'may' is the link.
Can you help me to learn more?
(Other definitions for emphysema that I've seen before include "Lung condition causes bad ESP mayhem" , "Respiratory disease" , "Serious lung condition" , "Distressing lung disease causing breathlessness" , "Lung problem causing breathlessness" .)
