Get submerged in washing place (4)
I believe the answer is:
sink
This might be a double definition.
'get' is the first definition.
(thesaurus)
'submerged in washing place' is the second definition.
'sink' can be an answer for 'place' (I have seen 'place of corruption' mean 'sink' so perhaps 'place' could also mean 'sink'). I'm not sure about the 'submerged in washing' bit.
Can you help me to learn more?
(Other definitions for sink that I've seen before include "Decline - in the kitchen" , "Disappear below the surface" , "Descend into water" , "Succeed in putting" , "Plunge down" .)
