Steps that may be taken (6)
I believe the answer is:
ladder
'steps' is the definition.
(ladder is a kind of steps)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ladder that I've seen before include "Household climbing device or hole in stocking" , "Climbing aid" , "Household climbing device or tear in stocking" , "1 [UNLUCKY FOR SOME]" , "A fire-fighter may use one" .)
