In torrid zones, tsunamis afford no snug retreats (5)
I believe the answer is:
nests
'snug retreats' is the definition.
(I've seen this in another clue)
'in torrid zones tsunamis' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NESTS' can be found hidden inside 'torrid zones tsunamis'.
'afford no' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for nests that I've seen before include "Bird houses" , "Birds' homes" , "Tables made to fit closely together" , "Sets of small tables that fit closely together" , "Bird structures" .)
