Unabating insect swarms surrounding hospital (9)
I believe the answer is:
incessant
'unabating' is the definition.
I can't judge whether this defines the answer.
'insect swarms surrounding hospital' is the wordplay.
'swarms' indicates an anagram (I've seen 'swarming' mean this).
'surrounding' is an insertion indicator.
'hospital' becomes 'san' (short for sanatorium).
'insect' anagrammed gives 'incest'.
'incest' enclosing '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" .)
