Concerning cry reveals status of GP at home? (2,4)
I believe the answer is:
on call
'status of gp at home?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'concerning cry' is the wordplay.
'concerning' becomes 'on' (both can mean 'in relation to').
'cry' becomes 'call' (synonyms).
'on'+'call'='ON CALL'
'reveals' acts as a link.
Can you help me to learn more?
(Other definitions for on call that I've seen before include "Like a doctor, perhaps" , "Available if needed" , "Contactable" , "ready to respond" , "available in emergencies?" .)
