Undiscovered monster still what gets inspector going (4)
I believe the answer is:
yeti
'undiscovered monster' is the definition.
'yeti' can be an answer for 'monster' (yeti is a kind of monster). I'm unsure of the 'undiscovered' bit.
'still what gets inspector going' is the wordplay.
I cannot quite understand how this works, but
'still' could be 'yet' (yet can mean still or so far) and 'yet' is present in the answer.
A single letter 'i' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for yeti that I've seen before include "Teh Abominable Snowman" , "whose existence is unconfirmed" , "An abominable animal!" , "Legendary Himalayan dweller" , "elusive character" .)
