Creature from the west (3)
I believe the answer is:
ewe
'creature' is the definition.
(female sheep)
'from the west' is the wordplay.
'from' indicates the answer is hidden within the clue.
'EWE' can be found hidden inside 'the west'.
(Other definitions for ewe that I've seen before include "Ram's partner?" , "Female on farm" , "She'll provide material to knit" , "Lamb supplier" , "21a [SHEEP]" .)
