Snored badly in low humming sounds (6)
I believe the answer is:
drones
'sounds' is the definition.
(droning is a kind of sounding)
'snored badly' is the wordplay.
'badly' indicates an anagram.
'snored' is an anagram of 'DRONES'.
'in low humming' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for drones that I've seen before include "Honeybees that mate with the queen" , "Bass pipes of bagpipes" , "Aircraft operated by remote control" , "Male honey-bee or idle people" , "Male bees or idlers" .)
