Like a shattering snore by a worker? (8)
I believe the answer is:
resonant
'like' is the definition.
(I've seen this before)
'a shattering snore by a worker?' is the wordplay.
'a shattering' is an anagram indicator.
'by' says to put letters next to each other.
'a worker?' becomes 'ant' (worker is a type of ant).
'snore' with letters rearranged gives 'reson'.
'reson'+'ant'='RESONANT'
(Other definitions for resonant that I've seen before include "Tending to reinforce sounds" , "Sonorous, full and rich in sound" , "Evoking memories" , "Deep and vibrating" , "Deep, clear and continuing to sound or reverberate" .)
