How's your father? Lacking stimulus after mountain scaled (8)
I believe the answer is:
platonic
'scaled' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'how's your father? lacking stimulus after mountain' is the wordplay.
I cannot quite see how this works, but
'stimulus' could be 'tonic' (I've seen this before) and 'tonic' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for platonic that I've seen before include "No-sex" , "Descriptive of a friendship-only relationship" , "Without physical desire" , "Non-sexual (friendship)" , "This sort of love is passionless" .)
