Like the cat that got the cream? (3)
I believe the answer is:
fat
'cream?' is the definition.
(thesaurus)
'like the cat that got the' is the wordplay.
'like the cat' becomes 'fa' (I can't explain this - if you can you should give a lot more credence to this answer).
'that got' says to put letters next to each other.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'fa'+'t'='FAT'
Can you help me to learn more?
(Other definitions for fat that I've seen before include "eg Lard" , "As Bunter" , "and 24: Overpaid City type" , "Obese, overweight" , "Greasy substance" .)
