Told to fashion a rod out of a reed, possibly (7)
I believe the answer is:
ordered
'told' is the definition.
(given orders)
'fashion a rod out of a reed possibly' is the wordplay.
'fashion' indicates an anagram.
'out of' indicates putting letters inside (some letters on the outside of others).
'possibly' indicates anagramming the letters.
'rod' anagrammed gives 'ord'.
'reed' is an anagram of 'dere'.
'ord' placed around 'dere' is 'ORDERED'.
'to' acts as a link.
(Other definitions for ordered that I've seen before include "Methodically arranged" , "Issued commands" , "Requisitioned" , "Told" , "Gave instruction, commanded" .)
