Can you iron it like lightning? (5)
I believe the answer is:
sheet
'lightning?' is the definition.
(sheet lightning is a kind of lightning)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sheet that I've seen before include "Item of bedlinen" , "leaf" , "Piece of paper or bedlinen" , "Single piece of paper" , "It usually gets blanket coverage" .)
