Vast coniferous forest where wild cat heard (5)
I believe the answer is:
taiga
'vast coniferous forest' is the definition.
'taiga' can be an answer for 'forest' (type of forest). I am unsure of the 'vast coniferous' bit.
'wild cat heard' is the wordplay.
'wild cat' becomes 'tiger' (I've seen this in another clue).
'heard' indicates a 'sounds like' (homophone) clue.
'tiger' sounds like 'TAIGA'.
'where' is the link.
Can you help me to learn more?
(Other definitions for taiga that I've seen before include "coniferous forests" , "trees" , "tree-covered region" , "Siberian subarctic forest(s)" , "Forested northern land" .)
