Thanks a lot for the titfer (3)
I believe the answer is:
tam
'titfer' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
'thanks a lot' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'a lot' becomes 'm'.
'ta'+'m'='TAM'
'for the' is the link.
Can you help me to learn more?
(Other definitions for tam that I've seen before include "Turn over the mat for a cap" , "Scots hat" , "Ratings compiled on TV listener numbers" , "TV audience ratings" , "Scotsman's cap" .)
