Makes a home that sinks gradually (7)
I believe the answer is:
settles
'sinks gradually' is the definition.
'settles' can be an answer for 'sinks' (settling is a kind of sinking). I'm not sure about the 'gradually' bit.
'makes a home' is the wordplay.
I cannot really see how this works, but
'home' could be 'sett' (type of animal dwelling) and 'sett' is found in the answer.
The remaining letters 'les' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'that' acts as a link.
Can you help me to learn more?
(Other definitions for settles that I've seen before include "Long wooden benches with backs" , "Becomes established in a place" , "Comes to rest" , "Pays the bill" , "seating" .)
