Fantastic beast still independent (4)
I believe the answer is:
yeti
'fantastic beast' is the definition.
'yeti' can be an answer for 'beast' (I've seen this before). I am not sure about the 'fantastic' bit.
'still independent' is the wordplay.
'still' becomes 'yet' (synonyms).
'independent' becomes 'i'.
'yet'+'i'='YETI'
Can you help me to learn more?
(Other definitions for yeti that I've seen before include "Legendary beast of the Himalayas?" , "Hairy recluse" , "Possibly a hairy creature" , "Feared creature" , "that is found in Himalayan mythology" .)
