Unabating insect swarms surrounding hospital (9)
I believe the answer is:
incessant
'unabating' is the definition.
I can't tell whether this defines the answer.
'insect swarms surrounding hospital' is the wordplay.
'swarms' is an anagram indicator (I've seen 'swarming' mean this).
'surrounding' is an insertion indicator.
'hospital' becomes 'san' (short for sanatorium).
'insect' is an anagram of 'incest'.
'incest' placed around 'san' is 'INCESSANT'.
Can you help me to learn more?
(Other definitions for incessant that I've seen before include "Continual and uninterrupted" , "Continuous" , "happening all the time" , "Persistent" , "Perpetual, unremitting" .)
