How one learns to walk gradually? (4,2,4)
I believe the answer is:
step by step
'gradually?' is the definition.
(I know that bit by bit can be written as step by step)
'how one learns to walk' is the wordplay.
I cannot quite understand how this works, but
'walk' could be 'step' (I've seen this before) and 'step' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for step by step that I've seen before include "Gradually" , "Incrementally" , "climb ladder thus" , "A bit at a time" , "advance via stair" .)
