Animal from heart of Tibet getting cross (4)
I believe the answer is:
ibex
'animal' is the definition.
(thesaurus)
'heart of tibet getting cross' is the wordplay.
'heart of' indicates the central letters.
'getting' is a charade indicator (letters next to each other).
'cross' becomes 'x'.
The central letters of 'tibet' are 'ibe'.
'ibe'+'x'='IBEX'
'from' is the link.
(Other definitions for ibex that I've seen before include "Sure-footed climber" , "Pyrenean mountain goat" , "Sure-footed type" , "one seldom puts a foot wrong" , "Mountain-goat" .)
