This is the only correct take with the etymology partitioning of the words.

There’s merit to change afternoon to mid day, midnight to its opposite, then using morning and evening for their opposites.

More correct words would be

Night = 6p-6a Day = 6a - 6p

Night= 9pm - 3am Morning = 3am - 9am Day= 9am - 3pm Evening = 3pm - 9pm

Instead day also has connotations of the entirety of the day. So in reality we just need a new word for the sunny part of the day… Sunday and Moonday! Wait… Lightday and Darkday! Wait…

Midnight… Midmorn… Midday… Mideve… Wait…

AfterNoon. AfterEve. AfterNight. AfterMorn. Wait…

You know what. Fuck midnight. I’m now calling midnight Onno. now. Since it sounds like emo, oh no, and is the opposite of noon.

I’ll continue the lingual tradition of purposely mispronouncing Onno as AhNo instead of OhNo though because you can’t have English being phonetic now…
