Which phrase fits the moment

Frequently Asked Questions

What is the best professional alternative to did you know?

“Just so you know” is the safest all-rounder for work emails, while “Worth noting” suits reports and “For your information” fits facts tied to a decision.

Is it rude to start a sentence with did you know?

No, but it can sound patronising if the listener already knows the fact. Softer openers like “You might not know this, but” avoid that risk.

What can I say instead of did you know in an essay?

Use “Interestingly”, “Notably”, or “It is worth noting that” in essays. They carry the same meaning without the conversational tone.

What is a fun alternative to did you know for social media?

“Fun fact” is the classic choice for captions, while “Bet you did not know” and “Here is a wild one” get more comments and shares.

How do I share a fact without sounding like I am lecturing?

Share it as something you just learned yourself: “Turns out” and “Here is something interesting” feel like discoveries, not lessons.

A good opener earns attention, it never assumes the listener knows nothing.
