There was a talk at a university, where the presenter used only words of two or less SYLABLES , but he allowed himself to use more complicated words after explaining them (but kept that to a minimum).

I can't find either the author or the talk. I think it was some 5 years ago.

At first, I thought it was Randall Munroe, but I might be remembering this: https://xkcd.com/thing-explainer/

I've also tried with Paul Graham, who has some articles trying to convey something similar, but no luck there.

Edited to add : I think the original proponent of a similar idea was Richard Feynman : https://www.hpcdan.org/reeds_ruminations/2022/03/understandi...
