Material for sails? (5)
I believe the answer is:
sisal
'material' is the definition.
(sisal is a kind of material)
'sails?' is the wordplay.
'sails' anagrams to 'SISAL'.
However, I am not sure how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for sisal that I've seen before include "Plant fibre used to make string" , "Sails (anag) - fibre" , "Fibre of Mexican agave" , "Fibrous plant used for rope" , "Rope-fibre made from leaves of tropical plant" .)
