There is a leader, like Narendra Modi, who is very fond of using things like,
the ‘5 Es’ of Economy, Environment, Energy, Empathy, Equity the '3 D's' India offers, Democracy, Demography, Demand
I am hunting for a word to describe such word groupings and use it in a sentence like:
Narendra Modi, famous for his ____ , enthralled the audience at Madison Square with his speech.
Edit: Based on WS2 and Hugh's answers, I believe the best phrase to describe such things would be alliterative mnemonics .
