Kid goat occasionally seen in dance (5)
I believe the answer is:
conga
'dance' is the definition.
(I know that conga is a type of dance)
'kid goat occasionally' is the wordplay.
'kid' becomes 'con' (I've seen this in other clues).
'occasionally' means one should take alternating letters.
The alternate letters of 'goat' are 'ga'.
'con'+'ga'='CONGA'
'seen in' acts as a link.
(Other definitions for conga that I've seen before include "Circuitous line dance" , "Latin American dance performed in single file" , "Latin American "follow-my-leader" dance" , "Dance performed in line" , "Serpentine dance" .)
