Rope used for mooring ships (5)
I believe the answer is:
cable
This might be a double definition.
'rope' is the first definition.
(I know that rope can be written as cable)
'mooring ships' is the second definition.
'cable' can be an answer for 'mooring' (thesaurus). I'm not certain of the 'ships' bit.
'used for' is the link.
Can you help me to learn more?
(Other definitions for cable that I've seen before include "Communication - wire - 200 yards in length" , "Rope for communication" , "Strong thick rope made of twisted hemp or steel wire" , "Communications wire" , "This may pull car up" .)
