In this country you might hear an insect (4)
I believe the answer is:
laos
'in this country you might hear' is the definition.
'laos' can be an answer for 'country' (Laos is an example). I am not sure about the remainder of the definition.
'an insect' is the wordplay.
I cannot really see how this works, but
'an' could be 'a' and 'a' is present in the answer.
The remaining letters 'los' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for laos that I've seen before include "South-east Asian republic, capital Vientiane" , "Landlocked state in southeastern Asia" , "Country between Thailand/Vietnam" , "SE Asian country" , "Republic of southeast Asia" .)
