Difficult situation in wet low-lying ground (8)
I believe the answer is:
quagmire
'difficult situation' is the definition.
(I've seen this before)
'wet low-lying ground' is the wordplay.
'wet low lying' becomes 'quag' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ground' becomes 'mire' (mire is a kind of ground).
'quag'+'mire'='QUAGMIRE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for quagmire that I've seen before include "Swampy marsh" , "Bog - impasse" , "Wet bog" , "Boggy ground" , "Morass" .)
