Do those have different definitions though? If I do something ‘by purpose’, I don’t think it means anything different from doing it ‘on purpose’. What other meaning could we derive from that?

I’ve always thought the same, but one day I realized the opposite of ‘by accident’ is ‘on purpose’. They’re both prepositions and nouns, so why couldn’t we say ‘on accident’ and ‘by purpose’? They’re at least grammatically correct if not socially.

You might have meant it as a joke but just in case someone else isn’t aware, this button actually made your CPU slower 🤓

Which comes in a bottle and doesn’t save money haha
