Listen out for openings (6)
I believe the answer is:
inlets
'openings' is the definition.
The answer and definition can be both natural objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'listen out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'listen' with letters rearranged gives 'INLETS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for inlets that I've seen before include "Silent sort of coves" , "Small arms off larger bodies of water" , "Silent sort of sea strips" , "Small bays of silent kind" , "Sounds" .)
