It hasn't been. It essentially means "below." "Substandard" is a synonym for inferior, but it literally means "below standard." In most cases, the prefix is merely descriptive, not judgmental or indicative of quality.Sucks how the word 'sub' has been changed to mean 'inferior'. As that's not what it's meant to mean.
A subspecies isn't inferior to a species. Any more than a species is inferior to a genus.
Anyone who disagrees, I challenge them to pit a marine against a submarine in aquatic combat and see which wins.
