Exemplifying the total dynasty (7)
I believe the answer is:
summing
'exemplifying' is the definition.
The answer and definition can be both to do with communicating as well as being present participle verbs.
Maybe you can see a link between them that I can't see?
'the total dynasty' is the wordplay.
'the total' becomes 'sum' ('sum' can be a synonym of 'total').
'dynasty' becomes 'ming' (I've seen this before).
'sum'+'ming'='SUMMING'
Can you help me to learn more?
(Another definition for summing that I've seen is " Calculating".)
