Steps that can 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 remainder of the clue works.
Can you help me to learn more?
(Other definitions for ladder that I've seen before include "Framework for scaling, usually portable" , "Steps consisting of rungs" , "Hierarchical structure" , "sometimes with companion" , "Support for climber" .)
