Incorrect spelling

Saterday

Incorrect spelling, explanation: although some ways of pronunciation, especially British ones, may mislead a speaker to spell this word as Saterday, it is a mistake. The correct form, Saturday, comes from Old English word sæterdæg, which meant the day of Saturn, as it was the day of the planet Saturn and Roman god Saturn. Therefore Saturday is the correct form.


Correct spelling

Saturday

Correct spelling, explanation: Saturday is the correct form, because the word comes from planet Saturn (and at the same time Roman god of the same name). This day used to be called the day of Saturn, that is why it is spelled Saturday, not Saterday.
