From a height, see one toilet pest (7)
I believe the answer is:
aloofly
'from a height' is the definition.
I can't tell whether this defines the answer.
'one toilet pest' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'toilet' becomes 'loo' (loo can informally mean a toilet).
'pest' becomes 'fly'.
'a'+'loo'+'fly'='ALOOFLY'
'see' acts as a link.
Can you help me to learn more?
(Other definitions for aloofly that I've seen before include "Keeping apart from" , "Distantly" , "How to disconnect, perhaps" , "in a cold manner?" .)
