Thanks a lot for very little! (3)
I believe the answer is:
tad
'very little' is the definition.
'tad' can be an answer for 'little' (both can mean a small amount). I am not sure about the 'very' bit.
'thanks a lot' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'a lot' becomes 'd' ().
'ta'+'d'='TAD'
'for' is the link.
Can you help me to learn more?
(Other definitions for tad that I've seen before include "Small amount or degree" , "Slight amount" , "Smidgen" , "Little bit" , "little boy" .)
