Ballroom experts get it right to a _TÓ (5)
I believe the answer is:
tango
'ballroom' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'experts get it right to a to' is the wordplay.
I cannot quite see how this works, but
'get' could be 'go' (synonyms) and 'go' is present in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
'a' could be 'an' and 'an' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tango that I've seen before include "musical piece" , "Dramatic dance form Argentina" , "Dramatic ballroom dance from Argentina" , "Dance; T (radio comms.)" , "One from Argentina" .)
