Celebrate hosting top discussion (8)
I believe the answer is:
speaking
'discussion' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'celebrate hosting top' is the wordplay.
'celebrate' becomes 'sing' (as in to sing someone's praises).
'hosting' means one lot of letters goes inside another (inserted letters are welcomed in or hosted).
'top' becomes 'peak' (synonyms).
'sing' going around 'peak' is 'SPEAKING'.
Can you help me to learn more?
(Other definitions for speaking that I've seen before include "Saying something" , "Uttering" , "conveying meaning" , "a way of passing the word" , "Conversing" .)
