Little kangaroo let out to grub around (6)
I believe the answer is:
rootle
'grub around' is the definition.
(I've seen this in another clue)
'little kangaroo let out' is the wordplay.
'little kangaroo' becomes 'roo' (I've seen this before. I am not sure about the 'little' bit.).
'out' indicates an anagram (out can mean wrong or inaccurate).
'let' is an anagram of 'tle'.
'roo'+'tle'='ROOTLE'
'to' is the link.
Can you help me to learn more?
(Other definitions for rootle that I've seen before include "Search the ground as pigs do" , "grub" , "Dig (as pig for truffles)" , "Dig with snout" .)
