Fibre woven to make sails? (5)
I believe the answer is:
sisal
'fibre' is the definition.
(sisal is a kind of fibre)
'woven to make sails?' is the wordplay.
'sails' can be anagrammed to 'SISAL'.
However, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for sisal that I've seen before include "Hemp fibre" , "Plant fibre used for ropes" , "Fibre used in rope-making" , "Plant fibre used for making rope" , "Strong rope fibre" .)
