Unabating insect swarms surrounding hospital (9)
I believe the answer is:
incessant
'unabating' is the definition.
I can't judge whether this definition defines the answer.
'insect swarms surrounding hospital' is the wordplay.
'swarms' indicates an anagram (I've seen 'swarming' mean this).
'surrounding' means one lot of letters goes inside another.
'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" .)
