Gave orders that it should be lined (5)
I believe the answer is:
ruled
'be lined' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ruled that I've seen before include "with several lines" , "Made authoritative statement" , "Reigned or ordered" , "Exercised control over" , "Governed or commanded" .)
