Degrees of comparison are weird as they go in the "more" direction for almost every human language but not in the "less" direction.

For instance, there is hard, harder and hardest,
but if it goes in the other direction, it’s suddenly "less hard" and "least hard".

It’s even weirder for languages that don‘t fall back to the "more" form for long adjectives, like English does:
More retarded, most retarded.
Which is again symmetrical to the other direction with "less".

Just some shower thoughts…
