My definition of ugly is subjective, of course
Hear, hear, Max! For me, it is contextural as well as subjective - and ugly word spoken in the "correct" place is acceptable, and not too grating whereas the same word spoken elsewhere gives me an unpleasant feeling. But it is fine by me if ither people don't go along with this.

So, you-all can say "haitch" and I'll just be "grate"ful
