Old Tibetans may be seen as reluctant to change (9)
I believe the answer is:
obstinate
'as reluctant to change' is the definition.
I can't judge whether this definition defines the answer.
'old tibetans may be' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'may be' indicates an anagram.
'tibetans' is an anagram of 'bstinate'.
'o'+'bstinate'='OBSTINATE'
'seen' acts as a link.
Can you help me to learn more?
(Other definitions for obstinate that I've seen before include "Pig-headed" , "Stubbornly persistent" , "Stubborn, obdurate" , "Stubborn or unyielding" , "Blindly stubborn" .)
