Tea for two - and one more dance (3-3-3)
I believe the answer is:
cha-cha-cha
'dance' is the definition.
(type of dance)
'tea for two and one more' is the wordplay.
I cannot really understand how this works, but
'tea' could be 'cha' (cha is a type of tea) and 'cha' is found within the answer.
'one' could be 'a' (a thing is one thing) and 'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cha-cha-cha that I've seen before include "Latin American dance, sounds trebled" , "Ballroom dance" , "A Latin American dance, very repetitive" , "Latin American dance - 1-2-3 rhythm" , "Latin-American dance" .)
