Noise from grand little pig (5)
I believe the answer is:
grunt
'noise' is the definition.
(I know that grunt is a type of noise)
'grand little pig' is the wordplay.
'grand' becomes 'g' (G is short for grand as in a thousand).
'little pig' becomes 'runt' (I have seen 'Undersized pig' mean 'runt' so perhaps 'pig' could also mean 'runt'. I am not sure about the 'little' bit.).
'g'+'runt'='GRUNT'
'from' is the link.
Can you help me to learn more?
(Other definitions for grunt that I've seen before include "Sound made by a pig" , "Snort (like a pig)" , "Noise of a pig ..." , "Inarticulate sound" , "Oink" .)
