What dog might do to get bigger meal, finally? (5)
I believe the answer is:
growl
'what dog might do' is the definition.
The definition suggests a singular noun which matches the answer.
'get bigger meal finally?' is the wordplay.
'get bigger' becomes 'grow' (I've seen this before).
'finally?' says to take the final letters (I've seen 'finally' mean this).
The last letter of 'meal' is 'l'.
'grow'+'l'='GROWL'
'to' is the link.
Can you help me to learn more?
(Other definitions for growl that I've seen before include "Show aggression as boxer" , "threatening sound" , "Menacing animal sound" , "Snarl" , "Hostile murmur" .)
