Article taken from old Iranian's shelter hard to get rid of (10)
I believe the answer is:
persistent
'article taken from old iranian's' is the definition.
I can't judge whether this definition defines the answer.
'shelter hard to get rid of' is the wordplay.
I cannot quite see how this works, but
'shelter' could be 'tent' (canvas shelter) and 'tent' 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 persistent that I've seen before include "Unrelenting - prettiness (anag)" , "Resolute - interminable" , "not giving up" , "Continual" , "Not taking "no" for an answer" .)
