one

/wan/

When used as a pronoun to refer to people in general (e.g., "One must be careful"), it sounds very formal. In everyday conversation, most people use "you" instead. When using "one" to replace a noun already mentioned, make sure the noun is singular. For plural items, you should use "ones" instead (e.g., "I like those red ones").

Can you pivot those slides to just one? We need to lean into the simplicity.

Sarah

I'm already burnt out. I can't possibly cram all that data onto one.

💡
David uses corporate jargon ('pivot', 'lean into') to request a slide reduction. Sarah responds using the phrasal verb 'burnt out' to express her exhaustion and uses 'one' as a pronoun referring back to the 'slide' mentioned by David.
