Dance companion for daughter in Russian cottage (3-3)
I believe the answer is:
cha-cha
'dance' is the definition.
(I know that cha-cha is a more specific form of dance)
'companion for daughter in russian cottage' is the wordplay.
'companion' becomes 'cha' (Companion of Honour).
'for' means one lot of letters go next to another.
'daughter in russian cottage' becomes 'cha' (I can't explain this - if you can you should give a lot more credence to this answer).
'cha'+'cha'='CHA-CHA'
Can you help me to learn more?
(Other definitions for cha-cha that I've seen before include "Modern ballroom dance from Latin America" , "Latin-American dance" , "certain steps" , "Repetitive Latin American dance" , "Latin American ballroom dance" .)
