Honour nurses taking risks lacking clothing related to treatment (9)
I believe the answer is:
medicinal
'nurses taking risks lacking clothing related to treatment' is the definition.
I can't tell whether this definition defines the answer.
'honour' is the wordplay.
I cannot really understand how this works, but
'honour' could be 'med' (MEd is an example) and 'med' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for medicinal that I've seen before include "analeptic" , "concerning drugs" , "Lily 15's invention" , "Having healing properties" , "of a health-giving nature?" .)
