Dance company not getting approval initially (5)
I believe the answer is:
conga
'dance' is the definition.
(I know that conga is a type of dance)
'company not getting approval initially' is the wordplay.
'company' becomes 'co' (abbreviation).
'initially' indicates taking the first letters.
The initial letters of 'not getting approval' is 'nga'.
'co'+'nga'='CONGA'
(Other definitions for conga that I've seen before include "Circuitous line dance" , "Long-line dance" , "What gets line moving rhythmically" , "wiggling line" , "Lined-up dance" .)
