@candle @sempervirenx Sorry, I shouldn't encourage thinking of those things as *weirdness* though, it always has a reason. It's just that sometimes it goes back too far to still make sense...
This "n into m" thing, for example, comes from latin: they didn't have nasals, so pronouncing 'n' immediately followed by p/b was hard, and the switch to lip-pressing m made perfect sense.
We just kept that even after the nasal vowels emerged, because we don't ret-con common words' spellings when the reason fades away... ^^°
