Yes, it’s got a whole load of meanings, not just male bees or bombs-on-presidents!
I used to tease my uni students by “droning” on like them…finishing with “amen” just to make them realise, with a laugh, how boring they were. Drone means to speak in a flat, boring, way, losing your listeners’ interest on the way!
I always find it very embarrassing when I tell my students that they need to speak well. The reason? I’ve been in Italy for a long ,long time and I still speak like Stan Laurel!
But the point is this: People can understand me because Italian is a pretty straightforward language to speak, whereas if you don’t get English pronunciation right, you’ll be misunderstood, AND, what is worse, you’ll have difficulty understanding others.
