Current's rising with ships stuck in silt (8)
I believe the answer is:
sediment
'silt' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for sediment that I've seen before include "Lees" , "End times (anag)" , "Remains" , "Matter settling (on seabed)" , "Stuff that settles to the bottom" .)
