Walk stiffly, rather like a stork (5)
I believe the answer is:
stalk
'walk stiffly' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stalk that I've seen before include "Stem; pursue stealthily" , "Follow prey stealthily" , "Quietly pursue" , "Stem of plant" , "Shadow" .)
