The type to show little gratitude (3)
I believe the answer is:
rat
'the type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'show little gratitude' is the wordplay.
'RAT' is hidden within the letters.
However, I'm not sure how the hidden word is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for rat that I've seen before include "Betray like a rodent" , "person doing shopping" , "Change sides" , "Desert - rodent" , "Cad" .)
