Still one unresolved Himalayan myth (4)
I believe the answer is:
yeti
'himalayan myth' is the definition.
(I've seen this in another clue)
'still one' is the wordplay.
'still' becomes 'yet' (yet can mean still or so far).
'one' becomes 'i' (Roman numeral).
'yet'+'i'='YETI'
'unresolved' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for yeti that I've seen before include "Legendary Himalayan creature" , "Mythical Himalayan beast" , "creature never actually seen" , "that is found in Himalayan mythology" , "creature awaiting discovery?" .)
