Little animal close to granite block (4)
I believe the answer is:
cube
'block' is the definition.
(I know that block can be written as cube)
'little animal close to granite' is the wordplay.
'little animal' becomes 'cub' (cub is a kind of animal. I am not sure about the 'little' bit.).
'close to' indicates one should take the final letters (the 'close' to the word).
The last letter of 'granite' is 'e'.
'cub'+'e'='CUBE'
Can you help me to learn more?
(Other definitions for cube that I've seen before include "Square-sided solid" , "Rubik invented a puzzling one" , "For instance, eight" , "Square-sided body" , "Regular 3-D shape" .)
