Eggs on following it's clapping (7)
I believe the answer is:
ovation
'clapping' is the definition.
(I've seen this before)
'eggs on following it's' is the wordplay.
'eggs' becomes 'ova' (term for egg cells).
'following' says to put letters next to each other.
'it's' becomes 'ti' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' after 'ti' is 'tion'.
'ova'+'tion'='OVATION'
Can you help me to learn more?
(Other definitions for ovation that I've seen before include "Stormy applause" , "Long period of applause" , "Show of appreciation" , "Sustained show of applause" , "Plaudits" .)
