Unintentional inhalation of carbon particles etc, results in docile son getting physician for monarch (7,7)
I believe the answer is:
passive smoking
'unintentional inhalation of carbon particles etc results' is the definition.
I can't judge whether this definition defines the answer.
'docile son getting physician for monarch' is the wordplay.
I cannot really understand how this works, but
'docile' could be 'passive' (I've seen this before) and 'passive' is found within the answer.
'son' could be 's' (genealogical abbreviation for son) and 's' is found within the answer.
'physician' could be 'mo' (abbreviation for medical officer) and 'mo' is found within the answer.
'monarch' could be 'king' (king is a kind of monarch) and 'king' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for passive smoking that I've seen before include "So seen as dormant, volcano" , "Danger from nearby cigarettes" , "brings no fresh inspiration" , "problem with breathing?" .)
